How to Build an LED Flasher Circuit with a 555 Timer Chip An LED flasher circuit is a circuit which flashes the LED meaning turns it ON OFF, ON OFF, ON OFF. The 555 timer chip is a very versatile IC, because when connected correctly, it can it can create pulses of current at specific time intervals decided by the resistor capacitor (RC) network. When a 555 timer creates pulses in this way, the LED doesn't stay constantly on. It only turns on at a pulse and then shuts off after the pulse has passed. Simple LED flasher circuits Wild Bohemian Basic LED flasher circuit using NE555 timer IC. This circuit consumes more power, but it's advantage is when you need a variable flash rate, like for strobe circuits. You can actually use this circuit as a remote control for strobes that have a remote input. Of course, it has many other applications besides strobes.
