Arduino Servo Control for Beginners
I managed to get my servo working with Arduino today using this tutorial. Nothing to special. The first time I tried nothing happened because I had the min/max pulse time setup wrong for the hitec servo. With the hitec servos the min pulse is 900µsec and the max is 2100µsec. Once I changed that it worked and should work for all hitec servos. I have looked at the Arduino servo libraries and they all seem unfinished or limited in one way or another. I am currently working on a sketch that will allow the control of up to 11 servos with analog inputs or serial commands. Also in the works is an Aduino servo shield.

Hi I have a question. I am trying to get the arduino servo control to work but im still having issues. Is there anything else that needs to be added at the end of the script. ? if not what kind of results are expected, so far i have no results in my hitec servo. Im assuming im supposed to modify the script somehow.
any help would be tremendously appreciated.

Well there are a couple of things i need to know first. Do you have a potentiometer hooked up to your arduino? What pins do you have it connected to and what pins do you have connected to your servo?

Hi. I am new, on the arduino.cc website there is different code to make my servo works. but now I would like to use a sound sensor as a switch for the servo. I am having a lot of difficulties to write a code. does someone has ideas?

Well depends on what you mean by a sound sensor? I need more info before I could comment.

very nice web site. My English is not so good, so I do not understandt it well, but it seems very good. Thanks

i will like to build a small robot…
i would like to have 2 wheels…
surely i need one servo by wheel?
somebody can explain me how to connect 2 servo on the arduino?

it would be better with other languages support, but thanks..

hi!
i constructed a servo project controlled by arduino that continously rotate from zero degree to 180 degrees then back to zero degree again and so on. could somebody help me to modify the program where it will rotate one complete cycle only from 0-180-0 then finish and no looping. thanks in advance.

how to connect 8 servos for a walking robot

That is part of the problem with a regular arduino is that you can’t connect that many servos. Something I hope to work on in the near future. But no promises.

Hi Brett,
If I want to use a high power servo do I simply share the arduino and servo grounds with the external power, then apply +6 to the servo from the external too?

Based on what I read here http://www.glacialwanderer.com/hobbyrobotics/?p=7 yes.
