Rgb Led Controller Circuit Diagram

How to wire the power supply for a single colour led strip.

Rgb led controller circuit diagram.

The circuit below makes use of a remarkable device a power mosfet metal oxide silicon field effect transistor. As said the circuit is built around cd 4029 ic and a few other external components. 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. The rgb led is a dynamic led because of the fact that it can light up to many different colors.

As per the suggested sequence format a simple design using a 4017 ic and a 4060 ic can be used for implementing the proposed rgb led controller circuit. 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. The type of rgb led we will use in this circuit is a common cathode rgb led. The finished module can be powered from any clean 5 volt dc supply source for driving the rgb led connected at the output of the circuit.

We can switch up to 10 a dc in a few microsecond on type we use here. 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. Depending on which anode gets 3v determines which color the led lights as.
