Automatic Street Light Controller Circuit Design Circuit Diagram This is a small low-cost automatic street light controller circuit based on the 555 timer and an LDR. Apart from the street lights, this circuit can be used in areas where you need to control anything on the light basis. So many other projects can be built using the 555 Timer IC. I will try to add more projects based on the 555 Timer. 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. One of the first things many do with it is to create a blinking light. But that's just one simple example of the many things you can do with this chip. You can also control motors, create an alarm, create a musical instrument, and much more. Let's start with an overview of the pins. 555 Timer Pinout
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
RGB Light Strip Controller Circuits Circuit Diagram
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
How The Night Light Circuit Works. The photoresistor and the 100 kΩ 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. 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. The clock signal from the debouncing stage is fed to pin 14 of IC 4017 which will switch the light strip's illumination color. By pressing any button on the IR remote you can switch to your desired illumination color, after white color which is the last one you can turn off the LEDs in the light strip and by pressing a button on the remote we can cycle through all the colors again.
