Flashing Light Circuit Diagram. This simple flashing light circuit is powered with 6 volts 0 5a and has a low current consumption when the light bulb is off. Three different ways to build a blinking led circuit.
The schematic diagram of the led flasher circuit we will build is shown below. Circuit diagram of flash lamp using 555 timer ic here the circuit consists of an a stable multi vibrator using 555 timer ic which creates a square wave. It s an inverter where the voltage at which it switches from low to high is higher than the voltage for switching from high to low.
Transistor t1 may be replaced with bc160 and t2 with bc140.
The rate that the led flashes is determined by the resistors r1 and r2 and the electrolytic capacitor c1. Repeat the above process for the second capacitor. In the lessons you learned that you needed an inverter for this circuit but there s one important point if you want to build this. The speed of the blinking by led is determined by the potentiometer connected to the 555 timer.
