Rgb Led Controller Circuit Diagram

The type of rgb led we will use in this circuit is a common cathode rgb led.

Rgb led controller circuit diagram.

The rgb led module. The circuit below makes use of a remarkable device a power mosfet metal oxide silicon field effect transistor. We can switch up to 10 a dc in a few microsecond on type we use here. We are building here a rgb bulb using red green and blue leds we just need to add a mechanism to control the brightness or intensity of these light individually to control the brightness we are using pwm pulse width modulation method with 555 time ic 555 timer ic can generate a pulse of variable width and width of pulse can control the duty cycle.

Referring to the shown diagram the 4017 ic and the 4060 ic are wired in a standard led chaser mode which is also quite popular with the name knight rider due to its specific running and. The rgb led is a dynamic led because of the fact that it can light up to many different colors. Depending on which anode gets 3v determines which color the led lights as. Wiring a white led strip or any other strip of single colour leds couldn t be easier simply connect your 240v mains supply ve and ve cables to the input terminals of your led transformer and connect your led strip s starter lead ve and ve again to the transformer s output terminals.

This is an led in which all the grounds of the leds are tied together common. Mosfet here acts like an electronic relay that can switch from off to on in a very short time and requires a miniscule control signal. As said the circuit is built around cd 4029 ic and a few other external components.
