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!

Controlling servo direction with arduino Answered

So, I'm trying to control two servo motors for a robotic arm. I can't seem to figure out how to make two servos go opposite directions at the same time. This is needed as I have two servos facing opposite directions driving the same beam (If they're told to go the same direction, because they are facing opposite directions, they'll rotate opposite directions). Currently I'm using this code to rotate them both: for(pos = 0; pos < 180; pos += 1)    {                                    myservo.write(pos);                  delay(15);                        } and then using the same code, only replacing the top part with   for(pos = 180; pos>=1; pos-=1) to return to the original position. How do I make both servos go opposite directions though, so they can both be used to lift a beam at the same time?

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.

Hi there. While testing some code on three servos using my picaxe 18m2 project board I initially had them powered of the 4x1.5v battery pack. This was working smooth enough, but because I eventually plan to power seven servos (for a robot arm project) I thought I'd try using a 7.5v wall transformer but they didn't seem to like this as the smoothness of movement was gone as they slowed and sped up and were jittery.  Is the 7.5 a bit much, a few resistors maybe? Or prehaps capacitors would smooth things out. I'm not overly electronically gifted, robot builders guide is all I've got to go on. cheers. john.

why won't my picaxe 18m2 project board work?

Hi there. So i connected a servo to output 4, joined the 0v lines, had the two power sources, downloaded the sample code etc. Nothing happened. I tested the system using the LED test from the picaxe manual and that was fine. I must have tried to work the servo off the project board twenty times, until I removed the 18m2, placed it on a solderless breadboard, plugged the servo into the board, joined it all together with jumpers and as soon as I connected power the servo started preforming the code I downloaded while the 18m2 was still in the project board. So why won't it work connected to the project board? I've tried using another output and a resistor on the signal line.  If anyone has experience of working servos off a picaxe project board I'd appreciate a step by step walkthrough. As usual its probably something simple. thanks.

Arduino & Servo problem - servo overshooting/inaccurate

Hello Forum! So I'm planning to build a robotic arm and I'm testing servos for direct response to input values in degrees, in order to later build a code for forward and inverse kinematics. My problem is as follows: I've written some code to pass numbers to the motor from the keyboard. But my motor seems to be horribly innacurate and... well when I tell it to set itself at angle 90, it goes to like 110 or so. And in order to go from 0 to 180, I must pass 165 instead, because the servo goes beyond a half-full angle. Is it the motors fault or there should be some kind of additional feedback loop somewhere? With reactions like those, I could hardly build an RC car, not mentioning a robot. I add the code and I have filmed issue.     vid 2:     vid 1: I count on you guys! Thanks in advance! #include Servo myservo; int Input(0); void setup() {   myservo.attach(9);   myservo.write(180);   Serial.begin(9600);   Serial.println("system initialized");   Serial.println("input configuration value: "); } void loop() {   while (1)     {         while (Serial.available())         {           Input = atoi(Serial.readStringUntil('\n').c_str());             if(!(Input<0 || Input>180))             {                myservo.write(Input);                delay(15);                  Serial.println(Input);                Serial.println("input configuration value: ");             }             else             {                Serial.print(Input);                Serial.println("?");                Serial.println("y u do dis?");                        }         }         break;     }   delay(15);

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'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!

Servo Mod help

Hi Every one thanks for looking at my post. I have a specific project where I need 8 servos which would need to rotate up to 360 degrees. Please note I do not need continuous rotation mod, which would make me loose servo angle control. Given that i ended up with 3 options 1. Buy a winch or sail servo - these are costly about $40 and not sure if they suite my need. 2. Add an additional gear with 1:2 or 2:1 ratio (not sure about the terminology) of the main servo gear ( attached to pot); Servo rotates about 230 degrees now, so limiting it to 180 degrees from code and with the additional gear and modification I can get a 360 rotation on the added gear and use that as my main servo drive. 3. Replace current potentiometer with a multi-turn one ( available for around $2) with similar resistance value, this along with the potentiometer gear stop peg removal would give more than 360 degree rotation. Servo control would not be effected as resistance value is same and angle must be limited from code to keep the potentiometer from going to the end limits. I am just preparing and calculating the current gear values to decide on the specs needs for the gear mod. I need to measure servo pot values to find a suitable multi-turn pot. I would really appreciate if any one could comment on my approach and any alternatives. I wish some one had tried these before and could share their experience. Thanks Satya

I need to make a device that can move two small servos within 0.01 or less degree rotation (yes, degrees, not radians!).  Currently, everthing I've seen comes up greater than half a degree.  It must have position feedback (stepper without encoder won't work), and the whole thing must fit in a 1/2"x6" tube.  It only needs to move maybe 30-40oz-in, but will always have that load (so backlash isn't a huge issue, but still should be minimal).  A COTS device is best, but it can be homemade, preferably under $50 or so, maybe up to $100 max.  It doesn't need to move fast or continuously, maybe 90 in 0.5 seconds.  It will be run by a microcontroller with a lot of IO pins, and PID control.  Any ideas, products or anything would be great, Thanks in advance.
