divit 0 Posted November 16, 2008 Report Share Posted November 16, 2008 I need to generate pwn signals at port 0.0-0.7 and port 2.0-2.7.The pwm signals should change their Ton period according to digital value received from the adc by each sensor.every pin will hav a different pwn signal according to correspoding value of the sensor.the sensor will basically be a 5k ohm pot .the pwm signals will run a servo motor.the servo motor should move between 0 to 90 degrees.I am also posting the schematic please help me out i need to do this for my final year project 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.

okura 0 Posted December 1, 2008 Report Share Posted December 1, 2008 Here how the project looks like Hi divit!! Nice project....!! Why dont you use simple circuits to drive your servos?? Way I look at it, it is simple to drive the 16 servos using nothing more than 16 555 timer IC, without any programming involved. Quote Link to post Share on other sites
