Let us know if you have any problems creating your circuit. Using good quality Led will provide accurate output.The voltage and current rating of the 555 timer are: – 15v & 200mA.Additional voltage cannot be provided within the 555 timer.The Led series registers used here prevent the Led from going to the Over Voltage.Here the resistor between the two ICs also provides the Triggering Pulse by a series of capacitors, this Component helps to supply two specific voltage supply.Now by entering the voltage through the connected resistor on the battery positive terminal, the yellow Led will ignite. Comparison of traditional LED traffic signal without timer and traffic light with timer integrated in yellow light module.Function: informing drivers how muc.The length of the red LED will depend on the capacitor charge.Here, the voltage on the input of the first 555 timer (U1) is given at the output at the pin 3 of the result, so that the red led will ignite.If you want to know the details, please read the circuit analysis. This way the 555 timer controls the Led like Traffic Light. When an input voltage is provided to the 555 timer the timer returns the output periodically. Here the Led is connected to the output of both the 555 timers.Led on-off through the 555 timer IC’s specific timing.Now connect the resistor to pin 3 of the U2 IC and connect the green led positive end in series and connect the other end to the negative of the battery.Again, connect the negative end of yellow led to pin 7 of the U2 IC. Now connect one end of the 220-ohm resistor to the battery positive and the other end to the positive of the Led (yellow).A simple project for beginners, that implements a Traffic. Then connect the pin 6 and 2 of the IC (U1 & U2) and connect it to the connected part of the resistor and capacitor. Were back guys In this video, were creating something new With electronics, using Arduino UNO.Now connect the negative end of the capacitor to the battery negative.Now connect the positive end of the capacitor to one end of the 47k register and connect the other end to the pin 3 of the U2 IC.Then connect the negative end of the red led at the pin 3 of the U1 IC and connect the positive edge to the battery positive.Now, connect the pin 2 and 6 of the U1 IC to the connected end of the resistor and capacitor.Now connect the first end of the 100k register to pin 8 of the U2 IC and the other end to the positive of the capacitor, the negative end of the capacitor to the negative of the battery.Connect of the number 1 pin of U1 and U2 timer to the negative point of battery.First, connect the pin 4 and the number 8 to the 555 timer (U1) and connect it to the battery positive.Let’s get started Required Materialsī: When you connect the circuit, try to understand the process and circuit diagram mentioned below. This type of project is not used anywhere but the project is very nice as a presentation. Today we will create a Traffic Light project with the help of some Component. Usually, when we walk on the road, Traffic Light can be seen at certain points of the road. It will tell the MCU whether the pins are Input or Output.Today, we have come up with another wonderful project. In the void setup() function, add the following. This indicates which light goes into which pin. ![]() whether you have connected your wires into the correct pins. ![]()
