Huge Servo?

I read the instructable on how to turn a servo into a a geared motor, but with that board that is taken out of the servo, could you attach that to any motor and make much larger servos? kc

Servos motion not smooth

Hi, im trying to program my servo to do a simple sweep (smooth motion). but instead it jerks a small degree everytime. the code i've used : #include Servo myservo;  // create servo object to control a servo void setup() {   myservo.attach(9);  // attaches the servo on pin 9 to the servo object } void loop() {   myservo.write(10);                  // sets the servo position according to the scaled value   delay(1000);                           // waits for the servo to get there   myservo.write(150);                  // sets the servo position according to the scaled value   delay(1000); }

servo controlled by arduino

Hi everyone and thanks for looking. I wanted to conrtol a servo using ardunio. This is what I want the servo to do, I want to be able to flip a switch and have the servo move. switch in "off" position, servo is at rest flip the switch to "on" position, servo moves 90 degrees and holds switch to "off" position, servo returns to rest position I am just starting out with arduino and really didnt know what was need to acomplish this. any help would be great. Thanks in advanced

Controlling two servos with one pin and a NOT-gate

Here's an interesting idea. It may be possible to control two servos independently with only one output pin and an inverter/NOT-gate. Normally, a servo is at its 'center' position when a pulse is 1.5 ms & its angle (or speed for continuous servos) is based on the difference between the length of time of the pulse it received & the base-time of 1.5ms. The servo itself does not react to the time BETWEEN pulses however. If the signal was inverted, the result would be a pulse with a time being that of the time between pulses of the initial signal. If the width of a pulse and the time between pulses can be independently controlled, then it would be possible to control one servo with the signal directly, and another servo using the inverted signal. I found something similar here [http://www.diyrc.com/reversers.htm] but it seems to be intended for 'reversing' the signal used to control one of the servos.

Servo Position

Hey i was trying to control the servo using joystick(potentiometer). i am but stuck at a problem when joystick is at center servo is at 90° when i move the joystick to left, servo sets at 0° and when i release the joystick it came back to its 90° but when i move the joystick to right, the server does sets to 180° but does not come back to 90° on release the joystick, it sets to a little more than 90° like 100° what could be the problem ? #include Servo servo; int sp ; int js_x; void setup() { servo.attach(3); } void loop() { sp= map(js_x ,0 ,1023, 0, 180); servo.write(sp); }

servos run on 6.5V, but how many amps?

I have five servos running off a picaxe sd21 servo controller and it will operate using four AA batteries, but I want it to run off a wall adaptor. Now theres plenty of adjustable adaptors on the market giving from 3V to 12V and I've seen one that might work for me that can be set to 6.5/ 7.5V, but does anyone know the suitable current range for my device.

After long time of searching, without success, i would like some help. I purchased one Sm-s4303r servo motor. My questions are: 1.How can i do it work for 3 seconds at normal speed and to stop it for example 12hours. To work 2 times per day. 2.What will be the suitable servo which can do 180° in every movement. I mean 180° now and the second (to complete the cycle 360) in 10 hours.. I would be glad if somebody could help me. Thanks, Chris

Increase Torque and Current inside Servo

Hi; I have a DC Servo motor. I want to increase its torque. It has 12volt and max 900mamp current gives 15kgcm torque. I want to remove the tiny DC motor and fix a 5amp 12volt big motor with metal gears. I want to ask " How can I give more current without burning the main SMD circuit board". If I place a battery in parallel to the motor terminals it can burn the circuit. Any ideas ?

need a cheap way to use a servo and switch on LED's with a remote

I need to move a small servo left and right and have it stay where I leave it and power 1 or 2 sets of lights with a simple remote but I have no idea how to achieve this apart from use a radio control transmitter/receiver and an electronic speed controller. I see there are lots of little devices out there that could work but being a noob at electronics I'm not too sure what will work. I found this, would something similar to that work? It is 12v, my servos would only take about 6v max though, same with the LED's, I suppose I could use something to lower the voltage output? Cheers.

Feature rich servo controller

Hi All, I'd like to write a servo controller that allows another system to offload some of the low level motion control work to the controller. This is primarily for amateur robotics applications. I'm trying to work out whether a controller implementing the features below would be replicating effort of existing open source drivers and not really worth the bother. Has anyone come across an existing controller that can some/any of the following? Position feedback Alterable traversal rate(s) changeable in real time (mid motion) Different seeking modes (acceleration, stall detection, hammering, error margins) Different communication modes (position queuing, position interrupts, upstream arrival and stall messages, etc) and so on... I'm looking at doing this probably with an Ardunio Nano and controlling as many servos as possible, but the primary goal would be feature richness. I could also see applications for an Attiny version (1 controller to 1 or 2 servos, limited feature set). Has anybody got any thoughts on the idea? Thanks in advance, Andy

NEED HELP WITH CODING

Hello i would like to know if you guys could help with a code to make a servo reacts to an ultrasonic sensor. The way it would work is that when an object gets close to the sensor for example 2 inches, then the servo goes from 0 degrees to 135 degrees, then wait 5 seconds and go back to original position ( 0 degrees). i was thinking of using loop. something like . loop if  sensor is close to 2 inch then servo goes from 0 to 135 degrees then delay 5 seconds and go back from 135 to 0 degrees else do nothing end if end loop

Servo Help!

First of all, I'm not the best with Technology projects, just putting it out there in case its an obvious answer. Anyway, I have an arduino project that im working on. All it is is a servo that spins after 24 hours, I thought it would be a simple project (I've worked with arduino a little bit) and I wired it up correctly, I'm sure of that, but after I coded the program, the servo wouldn't spin! It just made a dull buzzing sound. At first  I thought it was my program, so i tried just about every basic "sweep" program i could find online about servos. Every program had the same result, a faint buzzing sound and no spinning. Next i thought, maybe the 5v wasn't enough to power the microservo, so i used a external 9v and ended with the same result, buzzing, no movement. Can Anyone Help me?! Please! Is it just a simple solution? Or is my arduino micro controller not working! Please help me because i would like to enter the project in a contest that ends soon! Thank You!

Why wont my servos react to my potentiometers

Hello everyone, hope your day is better than mine. I am trying to figure this out and to the best of my knowledge; I just can’t get this to work. Everything is connected correctly.  Note, I am also using separate power to the breadboard. The problem is, the servos adjust themselves when I apply power, but they will not turn when I increase or decrease the rotation of the potentiometers (I know all servos work and the pots work as well (trust me, I tested each using a single servo and pot sketch) I am almost positive it is an oversight, and I have been staring at it so long that, well I am most likely am overlooking the problem. I would really appreciate your assistance. So here is the code: #include Servo pot1V;  // create servo object to control a servo Servo pot2V;  // create servo object to control a servo Servo pot3H;  // create servo object to control a servo Servo pot4H;  // create servo object to control a servo int mypan1 = 0;  // analog pin used to connect the potentiometer int val0;    // variable to read the value from the analog pin int mypan2 = 1;  // analog pin used to connect the potentiometer int val1;    // variable to read the value from the analog pin int mytilt3 = 2;  // analog pin used to connect the potentiometer int val2;    // variable to read the value from the analog pin int mytilt4 = 3;  // analog pin used to connect the potentiometer int val3;    // variable to read the value from the analog pin void setup() {   pot1V.attach(3);  // attaches the servo on pin 9 to the servo object   pot2V.attach(5);  // attaches the servo on pin 9 to the servo object   pot3H.attach(6);  // attaches the servo on pin 9 to the servo object   pot4H.attach(9);  // attaches the servo on pin 9 to the servo object    } void loop() {   mypan1 = analogRead(0);            // reads the value of the potentiometer (value between 0 and 1023)   mypan1 = map(mypan1, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180)   pot1V.write(val0);                  // sets the servo position according to the scaled value   delay(15);                           // waits for the servo to get there   mypan2 = analogRead(1);            // reads the value of the potentiometer (value between 0 and 1023)   mypan2 = map(mypan2, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180)   pot2V.write(val1);                  // sets the servo position according to the scaled value   delay(15);                           // waits for the servo to get there   mytilt3 = analogRead(2);            // reads the value of the potentiometer (value between 0 and 1023)   mytilt3 = map(mytilt3, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180)   pot3H.write(val2);                  // sets the servo position according to the scaled value   delay(15);                           // waits for the servo to get there   mytilt4 = analogRead(3);            // reads the value of the potentiometer (value between 0 and 1023)   mytilt4 = map(mytilt4, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180)   pot4H.write(val3);                  // sets the servo position according to the scaled value   delay(15);                           // waits for the servo to get there } Thank you so much in advance, Anna :)

Picaxe and Servo problem

Ive been using this picaxe uC for a while and have had no problems, but in my latest project I wanted to pan a servo back and forth. Problem: for the life of me I can only get the servo to move in one direction. It is a GWS pico servo and I have "operated" it on 5v and 6v, so i dont believe it to be a voltage issue. coding issue perhaps? ( I have tried the SERVO command, the SERVO and SERVOPOS command, and even the correct PULSOUT commands to no avail) I have scoured other forums, even rev-ed.com's, but no one seems to have my same problem. As far as I know the SERVO command SHOULD work fine but doesnt. I have tried the commands with and without a 220 ohm resistor on the signal wire, but this seems negligible. When my picaxe 18x is loaded with any servo capable code and the connections are all hooked up, the servo simply moves all the way and stops. the only way i can "reset" my servo to its original position is by quickly removing and tapping the V+ or GND supply wire to the servo. after the servo has moved I can feel the tiny motor jiggle whenever I tap the signal wire as if trying to work. ANY suggestions are welcome!

Arduino and Servo Motor Control

I was wondering if I could control higher voltage servos (lets say off a 18v battery, more than my arduino board can handle) by building a separate circuit for my servos power and ground wires and putting my servo's Input/output (or pulse if you prefer) wire directly into the arduino board's sockets.  Would this a) damage my arduino? and/or b) effectively regulate servo positioning? (fritzing file attached).   Or would I be forced to use relays?        Thanks, Authority28

sensors and servos

I am working on a piece where I need to hook up 7 servo motors to the arduino (each rotating at a different speed, some in one direction, others in the other) but basically an on/off with a motion sensor. I am using a full rotation servo. I amusing an infrared sensor but the servo is still moving (awkwardly and jerky) when not sensing motion, but then runs as normal.Here is the code I am using (right now, I am only at 1 servo – trying to get the sensor right first) : #include Servo myservo;int potPin = 0; //analog pin used to connect the sensor int ledPin = 9; //select pin for the servoint val = 0; //variable to read the value from the analog pin void setup(){   myservo.attach(9); //set up the servo as usual pinMode(ledPin, OUTPUT); //variable to store the value coming from the sensor   Serial.begin(9600); //for watching the speeds in the serial monitor} void loop() { val = analogRead(potPin); // read the value from the sensor   val = map(val,0,600,0,255); if (val>80) digitalWrite(ledPin, HIGH); //turn the ledPin on    else if (val<80) digitalWrite(ledPin, LOW); //turn the LedPin off   Serial.println(val); delay(10); } – any suggestions?

Pushbutton Servo Control with a 555

I've found numerous write-ups on getting a servo working with a 555 IC but it's not quite the functionality that I'm looking for. What I'm trying to do is have two buttons go to a predetermined position but the write-ups have two buttons that just go clockwise or counterclockwise. I know this can be done with an Arduino but I'm trying to avoid that route so I can keep the footprint as small as possible. I've attached a picture of the schematic I was working from.

A couple of servo related questions.

I was thinking of doing some sort of robotics for the upcoming microcontroller contest, and need to reduce the weight of my design. So, try and lighten the battery pack, and give more current, I want to use 2XAAA @ 3V, instead of regulating a 9V cell down to 5V. The PIC supposedly will run on 2V. So the question is, how well will a servo perform on 2.5 to 3.0V, and what will the current draw be with a light load (I have heard that they can draw a couple of amps with a very heavy load).  Also, I have some 4V lithium ion cells out of a laptop, and need to charge them (They last so long on one charge, that I have not had to charge them since removing them from the laptop).

Running several servos off an Picaxe 18m2.

Hi there.  I recently got a Picaxe 18m2 project board and I want to run up to eight servos off it, if thats even possible. Would I need a separate servo driver/controller for that number of servos or perhaps a different microcontroller? Any examples of code for operating more than one servo at a time would be appreciated also.  By the way, apart from reading 'Robot builders bonanza', my technical experience consists of operating 'Bigtrak' when I was about 12 and changing the odd plug. Cheers.

Arduino/ESP8266/servo noise when idle

Hello everyone My project involves a robot with LEDs, servos and an Arduino with a Sparkfun ESP8266 shield on top.

on attiny85 chip, how to control servo motor with IR sensor?

Hi i would like to know the coding which is to control servo motor for using IR sensor on attiny85 chip. i can do with arduino but attiny85 is not same as it. what i want to control is simple press button (0x01FE847B) to move servo motor 180 degree press button (0x01FE44BB)to move servo motor 0 degree https://photo.cloud.naver.com/v2/# please help me

Hoe to 180 degrees servos, when they go only 160 !?

Hello instructables people! I have been trying for hours & hours, to solve a problem i have, with a couple of servos, and i hope that you will be able to help me understand how to solve that problem!   I have this robot, that i am trying to build, with an Arduino and 2 of the following servos:   http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=3714   When i move the mouse, i need both servos to move exactly the same direction and speed. This already works for me great, using a code i got here on Instructables! (https://www.instructables.com/id/Overview/).   The problem is, that 180 degrees, is critical for my robot, and i get only ~160 degrees...   I tried to use the same servos model, but converted to continuous rotation, but could not get the absolute movement and position sync accuracy, of both servos, in relation to one another, that i got with the non-continuous rotation servos.   So, i returned to the regular, unconverted servos, and purchased the following servo stretchers:   http://www.readymaderc.com/store/index.php?main_page=product_info&cPath;=11_15&products;_id=171   But, when i connected these stretchers, between the Arduino signal and the servos, things did not get better, but worse, and the servos started jerking and hardly reacting to mouse movements.   I have been spending hours & hours, with no success and am quite desperate...   Can you please help me!   Thanks a lot!

Moving Three Servos at Once

Hey Guys, I'm working on a project and I'm trying to figure out what power supply to use.  I have power supply rated for 5V and .7A.  I was going to test this power supply out by making all servos sweep back and forth at once, and see how it performs.  This question is main for the coders out there.  Is the following code correct?  I've had a long work day and I'm about to pass out and I was hoping if someone could critique this real quick.  Thanks in advance! /* Sweep by BARRAGAN This example code is in the public domain. modified 8 Nov 2013 by Scott Fitzgerald http://arduino.cc/en/Tutorial/Sweep */ #include Servo myservo01;  // create servo object  Servo myservo02: Servo myservo03: int pos = 0;    // variable to store the servo position void setup() {   myservo1.attach(9);  // attaches the servo on pin 9   myservo2.attach(8);   myservo3.attach(7); } void loop() {   for(pos = 0; pos <= 180; pos += 1)     // goes from 0 degrees to 180 degrees   {                                                                 // in steps of 1 degree     myservo01.write(pos);                      // tell servo to go to position 'pos'     delay(15);                                             // waits 15ms for the servo     myservo02.write(pos);     delay(15);     myservo03.write(pos);     delay(15);           }   for(pos = 180; pos>=0; pos-=1)     // goes from 180 degrees to 0 degrees   {                                    myservo01.write(pos);            // tell servo to go to position 'pos'     delay(15);                              // waits 15ms for the servo     myservo02.write(pos);                  delay(15);     myservo03.write(pos);                   delay(15);   } }

servo drive circuit

Does anyone know how to make the circuit like the ones inside srevo motors? I am designing a sumo bot with radio control. I need to use contenuously rotating motors with lots of power to drive the robot. I do know how to modify my servos so they contenuously rotate, but I don't think they will have enough power to push around the other robots. I would like to use one of my 12v gearmotors instead of the ones contained in servos, but I don't want to destroy my servos to do it.

Gears for Servos and Steppers

Hey guys (and gals), I've been researching this a lot, but I still haven't the solution.  When you are working on a project and you need a gear for your stepper or servo, where do you acquire it?  For example I work a lot with TowerPro 996 servos, but I haven't found any third parties selling gears for them.   Same thing for motors.  If you are using a stepper motor, like a NEMA or something where do you find a gear that attaches to it?

Arduino time base servo sweep code help

Hi,     I need help on creating arduino code for a time base sweeping servo. Specifically i would like to have my servo sweep 180 degrees and back to center every 20 minutes and repeat indefinably. Im sure its a fairly simple code but just new at coding in general I have looked at servo sweep code sample in the arduino library but I dont know how to implement it with a timer. Hope someone can help me out. thanks for your time uno r3, micro servo 99
