Mode Changeable LED Light Dimmer Circuit

Mode Changeable LED Light Dimmer

mode changeable Led Light is to adjust the brightness of the LED light using a Micro Switch. By pressing the Micro Switch in this Circuit the LED Brightness is changed in three modes.This is an easy LED Dimmer Circuit.

Dimmer Working Principle :

4017 Decade Counter IC is used in this Dimmer circuit. A micro switch is attached to the clock pin of this Decade IC and a VDD is attached to the another end of this switch. The first output is high when this switch is pressed. This output signal goes through the 4.7 K Resistor and switches the 13003 Transistor so that the LED at the output glows in the first mode. Then when the Switch is pressed for the second time, the Resistor Value in the second output is less and the LED in Mode Two is slightly brighter than the first Mode. so the Circuit operates in all three modes.
