Simple Traffic Light Circuit Diagram Using 555 Timer. Here the circuit consists of an a stable multi vibrator using 555 timer ic which creates a square wave. Although street lights have a shift time for 2minutes here we are reducing the time for testing the circuit.
In this project i will show you how to design police lights using 555 timer ic and cd4017 counter ic. The lighting example of the circuit is additionally same as the traffic signal lights. It generally consists of rectifier diodes 1n4001 a 5v regulator 7805 two timers circuit using ic 555 two relays 5v single changeover three 15w 230v light bulbs and also several read more.
The circuit shown here simulates the police car lights.
In this red led s are flashed for three times and blue led s are flashed for three times alternately. This time duration can be changed by changing the capacitor value. The circuit utilizes easily available electronic parts. Circuit diagram of flash lamp using 555 timer ic.
