In this 555 timer project, I have shown how to make an LED chaser circuit using 4017 and 555 timer IC. The 555 IC will generate the clock pulse for the CD4017 IC which can be varied by the potentiometer.

Download the PCB Layout for this LED chaser from the following article

Required Components for 4017 LED Chaser circuit
555 Timer IC
CD4017 IC
10nF capacitor (C2)
10uF capacitor (C1)
1k resistor (R3)
10k resistor (R1)
10k POT (VR2)
5-mm LEDs (10 no)
IC Bases (8-pin & 16-pin)
Terminal connector (2-pin)

You can also connect the GATE of MOSFETs instead of LEDs to control multiple LED strings. Thus you can use this LED circuit for Diwali decor.

During the tutorial video, I have explained how to make homemade PCB from cardboard or Acrylic sheet for this type of electronics project. The running led light chaser circuit is simple and can be designed easily at the home.
