In general, generating an LED fade effect requires a microcontroller or another expensive circuit. We have built this low-cost LED fading board using an inexpensive 555 Timer. The 555 timer is used as an astable multivibrator, which generates low-frequency pulses, further, this pulse train is feed to the base of BJT transistor TIP122 with a […]

The project described here is small 5W LED driver, that can be used in variety of applications by changing the mcu code. The example code provided is a simple digital toggle switch using two tactile switches. One switch is used for power ON and the other for OFF. The on board small trimmer potentiometer helps […]
