PWM circuit

Hi,

Can anyone give me the PWM circuit of CD motor control with all the component value. I was looking for the snubber circuit and the MOSFET used.

Regards,
Bency
 
Did anyone know how i can use thyristor (SCR) as power switch to drive a 12VDC Motor and LDR to control the direction?? Please help me for my project. Thanks.

You can't, there is no way to conveniently turn it off.

If you visit the Robotics Section in this site there are about 100 topics regarding line followers/ light followers.

They are using this input sensors ex:LDR & IR in their robots.Also have plenty posts regarding how to control a speed of a motor.
