RGB LED Controller

RGB LED Controller

In this project, we will use a CD4017 Decade Counter IC to control three 12V LEDs and create an Awesome LED Chaser. Also in this Circuit, you can control not only 12V Light but also Ac 220v bulb and DC bulb. Three relays are used for this.

RGB LED Controller Working Principle :

CD 4017 decade Counter IC is used in this circuit, 555 IC is always used to give pulse to this IC but in this circuit pulse is given using RGB LED, when pulse is given the CD 4017 output turns on and off the relay through BC 547 Transistor. By turning the LED ON / OFF to get the chaser effect.

Layout Of PCB Given Below

How To Make? :

First I designed the Chaser Circuit on the Easy Eda website and created the gerber file. I uploaded this gerber file on the JLCPCB website and ordered 10 PCB which costs 2 dollars. PCB was delivered in 8 days. I bought the required components in the Electronic Shop and then I put all the components in the PCB and then soldered using the soldering iron and then cut the Excess Terminal and cleaned the PCB.
