Traffic Light Circuit Using 555 Timer And 4017. Traffic signal lights are very important to regulate vehicles and traffic on roads simple four way traffic light circuit is read more. Click here to watch the tutorial videonow a days controlling traffic is one of the major problem in all over populated cities population is rising so vehicles are also rising but roads aren t increasing.
Sequential circuits are used to count the numbers in the series. 555 timer acts as a pulse generator providing an input to the 4017 counter ic. This two way traffic light circuit using 555 and cd4017 achieves the functionality of a typical two way traffic light using two integrated circuits.
For the first pulse q0 becomes high and for second pulse q1 becomes high and so on again for 10th pulse q0 state becomes high.
All lights are implemented with 3 high intensity leds in series to be more noticeable in the day. For the first pulse q0 becomes high and for second pulse q1 becomes high and so on again for 10th pulse q0 state becomes high. Traffic light using 4017 and 555 to order this pcb first go to the website link below then click add to card then select the pcb color and quantity then click submit and after few minutes. Traffic light is designed with two timer ics 555 and three led indicators this circuit drives three leds with different time delay to provide stop wait and go signals on road.
