Changing and modifying Code

I found this site which satisfies everything i need for my project but the only thing is tht instead of using connecting to a PC i want to give the values from a ADC. i am posting the site and the codes can u plz help me editing it aacording to the circuit diagram in the next post




and also i will be using 5k ohm potetiometers as sensors in the circuit if any other sensor is better plz help me

heres wat i need to change it too

Port 0 isn't going to work very well without pullup resistors. Where do all the identically name nets called "SERVO" go to. Where do forward and reverse come from. You gotta a lota work to do.

It might be possible to do the project without a microcomtroller using just 555 timers

Papabravo
the forward and reverse are for another gear motor for the wrist and the servo names go to servo motors control pin as pwm signals

Blue for us its is compulsory to use a microcontroller of 8051 series or 89XX series
