This traffic light is made with the help of counter ic which is mainly used for sequential circuits. We connect a 100μf capacitor to the positive voltage supply and then to pin 2. To connect power to the 555 timer chip we connect about 5 15v to v cc pin 8 and we connect pin 1 to ground.
The figure below shows a very simple and useful project schematic of a time delay relay circuit using a 555 timer ic.
The 555 timer ic is an integrated circuit chip used in a variety of timer delay pulse generation and oscillator applications. The circuit is able to trigger the relay from few seconds to few minutes after pressing the push switch s1. We need to set 555 timer in monostable mode to build timer. This traffic light is made with the help of counter ic which is mainly used for sequential circuits.
