Description:
In this mini-project, I have shown how to make 4017 LED chaser circuit diagram only using RGB LED. You can easily make this simple led chaser circuit using only CD4017.
In this article, I have shared the circuit diagram, PCB layout, and all other details for this simple 4017 project.
Circuit Diagram of LED chaser
To make this simple LED chaser circuit I have used only a 4017 IC. Here the flashing RGB LED 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).
4017 LED chaser Schematic Diagram
This the schematic of the 10 LED chaser with only 4017 IC.
Here I have used a 9-volt adapter to supply the circuit. If you use the 9V battery then you may have to connect multiple batteries in parallel to supply the LED chaser circuit.
PCB Layout for 4017 LED chaser Circuit
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 in Layout.
Required Components:
- CD4017 IC
- 470-ohm 0.25-watt Resistors (2no) (R1, R2)
- RGB Flashing LED (5-mm)
- 5-mm LEDs (10 nos)
- Connector & IC Base
- 9V DC Adaptor
- Acrylic sheet or cardboard.

How to make PCB for this 4017 Project
Steps for making the volt level indicator circuit on PCB:
Step 1: Print the PCB Layout and stick it on Acrylic sheet or cardboard
While printing please check the PCB dimension mentioned in the PCB layout. After downloading the PCB layout, you can print the word file (.docx) on the A4 page.
Step 2: Drill the holes for the components on the PCB
Now, drill the holes on the PCB for components as per the PCB layout. Here, I have use 555 DC motor to drill the holes. You can also use hand drill for drilling.
Step 3: Place Connect all the components as shown on the PCB layout
After that place all the components on the PCB as marked on the PCB. Here I have used extra leads of the components to connect those components.
After that I have soldered all the components as per the circuit diagram.
Now, our 4017 LED chaser PCB is ready.
Connect 9V DC Supply
Here I have connect 9V DC adapter to supply the circuit.
