I understand this is a very broad question, but what I am trying to do is control bunch of servos using communication port on my PC. It doesn't have to be a GUI interface I just want to send a key stroke to the AVR, then AVR can convert that into PWM and rotate each servo based on what I have specified in my program. It sounds kind of simple but for some reason I can't find anything.
Please NOTE: I DO NOT want to use a servo controller. I am trying to make this with AVR and my own program. any suggestions/tutorials I can go through?
