How To Make 4 Way Traffic Light Control Using 555 ођ Traffic light signal plays an important role to control vehicles on the road. the four way traffic light uses a 555 timer ic and a counter ic cd4017. the 555 timer ic operates as an astable multivibrator. it produces a pulse that depends on the timing of the resistor and capacitor. the pulses are then fed into the clock input of the counter ic. So, the 555 timer ic acts as a square wave generator and generated clock pulses. this input change is to change the shifting time of the traffic light (leds). then the clock pulse from the ne555 timer ic goes into the clock input of the cd4017 counter ic. then the counter ic counts pulse and changes the output line (q) logic into high or low.
4 Way Traffic Light Using A 555 Youtube How to make 4 way traffic light control using 555 timer and cd4017 | 4 way traffic signal lightschematics and proteus simulation: marobotic 2023. 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 following schematic shows a four way diagram of traffic lights utilizing the 555 timer ic. the timer produces approximately 100ms of pulses over time. the on time then is 50ms and the off time is 50ms. changing the capacitor value will adjust the time. although street lights last 2 minutes in shift time, the time to test the circuit here is. The traffic light control system uses a worldwide color code (a specific color order to enable color recognition for those who are color blind). here we design a traffic light circuit timer ics 555 and three led indicators. this circuit drives three leds with a different time delays to provide stop, wait, and go signals on road.

Construction & working. this simple four way traffic light circuit has two stage one is timing & counting stage another one is indication lights stage. those indication lights are should be properly placed on four lanes. here timer ic 555 placed with timing resistor r1, vr1 and timing capacitor c1 based on these elements value output pulse. This way, we may call it a sequential traffic light system. the working and operation of traffic lights control circuit, the main ic is 4017 counter ic which is used to glow the red, yellow and green led respectively. the 555 timer acts as a pulse generator providing an input to the 4017 counter ic. the glowing time of certain led lights.
