dear friends i can able to control hitech series of servo. but the below servo is not working for the same program. the servo doesnt have any problem. is there any thing different timing for this kind of servo.
use microcontroller like PIC or AVR to control it, as "hameeds01" mentioned its ordinary servo motor which mean you have three terminals for supply, ground and servo signal, you will give pulses to this terminal from your microcontroller, you can use PIC16F877 or PIC18F452.
Try the following servo control code. Its written in C and compiled using MikroC for PIC16F870 microcontroller. Also a simulation in Proteus is included.
thanks friends for your reply. i am using 89s52 not pic. i am able to control hitech series of servos but the same code doesnt work the servo which i mentioned above such as vs1 and vs2
