60W LED Dimmer for 12V LEDs using 555 Timer

60W LED Dimmer for 12V LEDs using 555 Timer

The project shown here is a cheap 60W LED dimmer for 12V LEDs/12V LED strips. The circuit is based on the very popular, versatile, and low-cost 555 timer IC, NE555 IC generates a PWM signal and IRF540 MOSFET works as output driver for the LEDs. In this circuit the 555 IC used in an...
