How-To Tuesday: Arduino 101 potentiometers and servos

Check out makershed.com for a complete line of Arduino products.

This is the 3rd installment of my Aduino How-To Tuesdays. This week I am going to cover using another basic part, the potentiometer. I will also cover connecting a servo to the Arduino. Servos can be hard to control, but not with the Arduino! That's just another reason why I love this little micro-controller.

could be done in one line :)

myservowrite(map(analogRead(po­tpin), 0, 1023, 0, 179));

Np. If you need anything else just message me.

thanks i'll try that

Try re-installing the arduino software. Make sure you extract it to your desktop and have all the program files. Second make sure your using the right com port. That can be found in the settings of the Arduino Software.

Nice Tutorial

ok i made that but i didnt have a protoshield i got this: avrdude: stk500_getsync(): not in sync: resp=0x00 what is the problem?

[percaine]

could you do an esr meter circuit?

It's not a stepper motor - 0-179 is the degree... 180degrees is the range for most servo motors... 0-1023 is what is recieved from the pot.. 0 - 0V, 1023 - 5V

can someone tell me where to find an explanation of the arduino's "servo.cpp" code? I don't know where in the code it increments it's timer for the pulse width of an individual servo. I want to write my own version in C to use with a pic18f. Any Help useful, thanks!
