What was the purpose of the traffic light?

The traffic light has ended up being a stunning method to diminish a number of vehicle accidents and it adequately and intelligently controls the traffic jams in the modern era. This article depicts a project of a traffic light utilizing three 555 clock timer ICs.

How does a four way traffic light work?

OR gates By taking one traffic signal and look at what is inputs are connected to output 0 and 2 of the desired, a circuit is constructed which is 4017 decade IC. When the NOR gate is has low implemented for all the traffic lights in this 4 inputs it gives a high on its output which gives 2 ways design.

How does The NE555 traffic light controller work?

The NE555 IC works as an astable multivibrator to produce pulses. The time period of these pulses can be adjusted by the Potentiometer. It means the Potentiometer is used to change the shifting time of the Traffic light. Then the output pulse from the NE555 timer IC goes into the clock input of the CD4017 counter IC.

How does clock work on traffic light controller?

It means the Potentiometer is used to change the shifting time of the Traffic light. Then the output 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.

What kind of IC is used for traffic lights?

Sequential Circuits are used to count the numbers in the series. Coming to the working principle of Traffic Lights, the main IC is 4017 counter IC which is used to glow the Red, yellow and green LED respectively. 555 timer acts as a pulse generator providing an input to the 4017 counter IC.
