Flickering of LED using 555 Timer
Aim of the Experiment :
Flickering of LED using 555 Timer
Minimum Requirements :
555 Timer IC
9V battery or power supply
Voltage Regulator (7805)
Capacitor- 100uf, 0.01uf
1KOhm resistor
LED
Connecting wires
Working Principle:
It is the circuit similar to Astable mode means free-running mode, in this capacitor charges and discharges itself. So, LED will
automatically ON and OFF. No input or external trigger is required. It can be used as LED blinker, vehicle indicator light, signal flashlight etc.
