A VERY simple Arduino Servo Tutorial?

I'm pretty much new to the arduino stuff and I was planning on making a biped robot. But first before all of that I need to know how to use servos. :P Is there someone out there that can maybe post a very easy to understand tutorial of how servos work? I've read ladyada's tutorial on the arduino. So basically I understand all of that but I'd like to know how to control servos and how to program them.

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.

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   {                                    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?

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.

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!

Is there any BEC/UBEC capable of doing such a task? Could i use a combination of more than one (Three UBECS off of the same battery, all in parallel)? The servos that i am using are TowerPro MG995 Digi Speed servos. On a slightly different topic, are there any BECS/UBECS that can monitor the battery's voltage, and shut off when it drops below a certain voltage? Links would be great Thanks!

X Y Zach humbly asks for your help...

Hey there Brochachos,            Ok, having just dug in on my first project, I'm more than overwhelmed by the sheer volume of 'stuffs' I need to learn to accomplish my goal.  Howevever, having done a substantial amount of reading, I believe I've got a fairly focused question that can hopefully pull a concise answer out of the beautiful woodwork of this community.  Onward... I'm trying to interface a gantry style xy table that uses some softpots as positions sensors for the x and y axes.  I want to send this analog signal wirelessly to two servo motors that will respond to this analog signal accurately, with minimal latency, and no jitter. As a fairly new egg in the DIY self world, I stubbornly cling to Arduino for comfort and the xbee modules seemed like a good fit, but the workaround to transmit an analog signal seemed troublesome and the servos always seem to develop a Parkinson's syndrome of sorts. (at least with the builds I saw). The question...   What transmitter/receiver is both extremely amateur friendly, with regards to setup, and can also get the signal (sans Internet connection)  at least 100ft to the receiver where it gracefully manifests itself on the servos as smooth motion.  If you don't have a definite answer, pointing me in the right direction of relevant reading is also greatly appreciated.  If there is anything I've left out, just ask.  Thanks in advance, I love you, but not like that... -Z

Controlling a servo with a Micro-controller?

So I decided to spend some time to make a "gimbal" in a very loose sense. Basically I was experimenting using a square wave oscillator to generate the correct PWM to have a servo rotate between 0 and 180 degrees when a tilt sensor is tripped. After some research multiple sites said having a 1ms pulse every 20ms would have it move to the 0 degree position. Great so I will make a oscillator pulses ~1ms on one side and 19ms on the other. However this does not seem to be working. I am curious if it is a fault in my math or if the tolerance on the parts I am using are just too wide to be any good. Here is a diagram of my set-up with the values a came up with. One spot that may be weak is that I just notice someone somewhere mentioned using 50Hz for the timing I just used that number when I calc my figures. Any feedback?  Also a side note is that I have been able to move the servo in one direction only and by accident ( in fact it's what inspired this project) when C1 & C2 were 2.2nF and the R1 & R2 were 10k potentiometers that I turned until something happened. Now that I am trying on purpose no results.

Id Like help using a Linear Actuator and a locking mechanism with only one or two momentary switches, not toggle. Ideas?

Hello, I am healthcare professional and a DIY enthusiast, but not mechanically or electrically inclined.  Keep that in mind with your answers.   I am redoing my closet in the next few weeks and do not have the space or money for a large gun safe.  My idea is that when building this closet I will build a stand up drawer using several slide mechanisms for the motion.  To keep this hidden and secure and darn right cool I envision using a linear actuator to open and close this hidden drawer.  I will also be using one to two electric strike modules to keep this secure.  My goal is to have one secret hidden BUTTON (not switch) that will trigger the locking mechanism and shortly after if not simultaneously activate the linear actuator.  The key here is I want to push a momentary button, not hold it, not use switches ect, just hold it until the drawer is completely open.   Second motion will be either the same button or a different MOMENTARY BUTTON is depressed activating a reversal on the actuator until fully closed in which the locking mechanism should activate (always closed).   That is my goal, I'm open to servos and such if anyone can SHOW me how it is done.  If you can show me wiring that would be best as words just don't work as much as pictures or videos for me.  I greatly appreciate all your help in advance and please remember NO TOGGLE Switches or factory wired remote controls.  I'm open to all ideas except those.  Thanks again guys.  Love your work and ideas.   T
