Description

Four way traffic light circuit diagram using 555 Timer IC is shown in the above diagram. The timer here generates pulses of time period 100ms approximately. So the ON time is 50ms and OFF time is 50ms. This time duration can be changed by changing the capacitor value. Although street lights have a shift time for 2minutes, here we are reducing the time for testing the circuit.
