Electronics student here Circuit design for light sensitive LED Circuit Diagram By using this system manual works are 100% removed. Here we design an automatic street light controller using relay and LDR which senses the light actually like our eyes. We know LDR (Light Dependent Resistor) has been used in many applications and properly employing in-circuit LDR can act as a perfect light-sensing element.
Finally, if you're interested in designing your own traffic light controller system, you can follow the design principles outlined in the circuit diagram. With the right set of components and a basic understanding of electronics, you should be able to design your own circuit for efficiently controlling traffic lights.
Simple Traffic Light Controller Circuit Diagram
How The Night Light Circuit Works. The photoresistor and the 100 kฮฉ resistor make up a voltage divider. When there is a lot of light, the photoresistor will have low resistance, which means the voltage divider gives a low output voltage. So the transistor is off and cuts off the current to the LED. Which means no light. In this video, we demonstrate how to make a simple universal IR remote-controlled LED light using the NE555 timer IC. This DIY electronics project is perfect Here the simple traffic light controller which is could be used to educate kids rudiments of traffic light guidelines. The circuit utilizes easily available electronic parts. It generally consists of rectifier diodes (1N4001), a 5V regulator 7805, two timers circuit using IC 555, two relays (5V, single-changeover), three 15W, 230V light bulbs
In some places, there is no AC mains power available, right. So, in such cases, we cannot use AC mains based street light circuits. Thats where a solar-powered automatic LED street light system becomes a smart solution, right. So now the 3rd circuit design below shows how we can make a small solar street light circuit using very few parts.

As the name of the project "Traffic Light Control Circuit" suggests, the fundamental idea of this simple electronic project is to control the traffic via lighting signals. It can be used to avoid vehicular collisions and traffic jams as the system ensures the smooth flow of traffic even on the busy routes.
