In this electronics project, I have explained how to make simple LED chaser lights with CD4017 & 555 timer IC.
In this article, I have shared the required components, complete circuit diagram, PCB layout, and all other details for this simple 555 timer project.
LED chaser Circuit Diagram
To make this simple LED chaser circuit I have used a 555 timer & 4017 IC. Here the 555 timer IC will generate the clock pulse for CD4017 IC. Then 4017 IC will blink the LEDs in sequence as per the signal in the clock pin (14).
I have used a 5V DC supply, but you can also use the 12V DC supply (no changes required for 12V).
PCB Layout for LED chaser Lights
Please download the PCB layout, then print it on the A4 page.
Please check the PCB size while printing, it should be the same as mentioned.
You can also download the PCB Gerber file for this project.
