How To Make A Traffic Signal Circuit

Traffic signals are essential in helping to regulate traffic and ensure that vehicles and pedestrians have a safe, efficient way to travel. While traffic signals can be expensive to purchase and install, they can be made much more cost-effectively by constructing a traffic signal circuit. This article will explain how to make a traffic signal circuit using simple electronic components.

To begin, gather the required components. These include two relays, an AC power supply unit, a timer switch, and three LEDs of different colors (red, yellow, and green). Once all of the components have been gathered, arrange them in a circuit as illustrated in the diagram. Be sure to pay close attention to the polarity of the components, as it is important for the circuit to function correctly.

When the circuit is set up properly, connect the circuit to the power supply. Adjust the timer switch such that the green LED turns on immediately and the other two LEDs turn on at intervals determined by the timer setting. With the circuit now functioning, test it to make sure it is working properly.

Although building a traffic signal circuit may appear complicated, breaking down the process into its individual steps greatly simplifies the task. Furthermore, the effort put into making the traffic signal circuit pays off and provides a great reward: the assurance of safety and regularity when travelling through busy streets.
