Easier Approach to Electronic Projects

Random LED Flasher


This Project flashes 8 LEDs in random manner
 
The speed of random flashes can be changed by simply changing the Capacitor of 555 timer, on 2.2mf it flashes will be faster and on 10mF they will be slower
 
This pattern is mostly seen on Christmas trees and other type of decorations.

 

Parts Required:
  1. 10k & 47k
  2. 2.2mF or 10mF
  3. 555 Timer IC
  4. 4026 Counter IC
  5. LEDs x (8)
  6. 9V battery
