i tried this project its working fine with one motor if i tried to control second motor it only jerks so how to control two motors at different speed

Please don't create multiple threads.

Can you post a link to the project you are using.

@ shrynikjain
how you are controlling the two motors
may be u need some modification in code to eliminate the interrupts
or finally may be u need to changed the design to pic or any other controller

thank u for the reply yes its the problem with the code i have seen the videos for controlling multiple lamps using arduino
and they also use phase control with interrupt to control lamps phase can you help me to code for control of two motor using 8051 series controller
