555 LED Chaser

555 LED Chaser

This post explains how to create a 5 channel LED Chaser using 555 Timer IC and BC547 Transistor.This 555 LED Chaser acts like a Tail LED Effect.

555 LED Chaser Working :

When the 555 Timer IC is supplied, a low to high voltage is generated at its output. This voltage goes to the transistors connected to it. You can increase the number of LEDs by increasing the transitor.

555 LED Chaser Circuit

Components Needed :

  • BC547 Transistor – 5
  • LED – 5
  • 10k Resistor – 2
  • 680 ohms resistor – 1
  • 1n4007 Diode – 1
  • 1k Resistor – 1
  • 470uf Capacitor – 1
  • 4k7 Resistor – 2
  • 100uf Capacitor -1
  • Plain PCB

Tools Needed :

  • Soldering Iron
  • Soldering Past
  • Lead
  • Soldering Iron Stand
  • PCB Holding Stand
  • Ferric chloride
  • Mini Drill

How To Make :

I first created the Cicuit of Chaser on the Easy EDA site. Then I downloaded the PCB Layout in PDF and printed it on a photo sheet. Then I put this sheet on the plain PCB and taped it. Then I put the iron box and rubbed it for 5 minutes and then I put this PCB in hot water and took the photo sheet. Then I put it in Etching Solution and after 20 minutes I cleaned the PCB. Then I drilled the hole using a mini drill. Then I fixed and solder all the components and then cut the Excess Terminal.
