ES-32     PWM DC Light Bulb Dimmer / Motor Speed Controller
( DC  6 ~ 15V )

<<<<<< MORE kits .....  view other available kits >>>>>>

This kit controls the brightness of dc light bulb or the speed of small dc motor by PWM (pulse-width-modulation).  A two-transistor astable circuit generates a square wave with fixed frequency & varying duty cycle. The duty cycle can be changed by adjusting the  potentiometer (VR) .  The duty cycle of the square wave determines load power.  A Power MOSFET is used to drive the load.

Applications : 
DC motor speed control or light bulb brightness control
