    I am making a dex hand which works on an adc and AT98S52.
    I dont knw how to program a ic i have the circuit diagram i just need help if some 1 could giv me the coding for it. There are 16 sensors (i am using 5k ohm pots as sensors) .The sensors are given to the adc the adc will generate a digital value and give it to micro controller.The micro controller will then generate a pwm signal .The pwm signal is then given to the servo motors. I basically need a program which will enable each servo motor to move according to the adc value received.Therefore each each pot will drive a single servo motor.

    You could try AVR Freaks but doubtful anyone is going to write your program for you.

    It's your diploma, you're supposed to be doing work. When's it due?

    At $14 you may not have too many programmers lined up.

    Why wouldn't your group pick a project they can complete themselves?

    Hello divit, why have you selected an Atmel chip, are you familiar with it ? What programming experience do you have with this type of project ?

    It seems you need to convert an analog signal to PWM to control a standard hobby servo unit, is this correct ?

    This doesn't address programming your project, but you really want PNP transistors for your high-side units in the H-Bridge...

    I am not familiar with it cause its my 1st project with micro controllers i am only 17 ,we are restricted to a very few micro controllers and also i can choose another Circuit but i will have to have somethign related to it cause i need to build a hand robot and that pwm signal is gonna drive servo motors
