1/12/2024 0 Comments Arduino traffic light with timerHere we can modify delays for which the Red, yellow and Green light remain on and off. This process is looped in void loop() function for continuous process. Then yellow on the left side glows for 1sec followed by green one, leaving upside and right side Red with 5sec delay. upside and left side is red) closed with Red Light and 5seconds delay. Then the yellow light gets turned on at the right side for 1sec followed by the Green light, leaving other two sides (i.e. left side and right side) remains closed with Red signal, with a delay of 5 seconds. First the upside/forward side is opened (green), while the other two sides (i.e. This process is well demonstrated in the Video Below. Then in void loop() function we have written the code for traffic lights to be turned on and off in sequence as mentioned above.ĭigitalWrite(2,1) //enables the 1st set of signals In the program, first we have declared pins (2,3…10) as output in void setup() for 9 LEDs (three on each side i.e. And yellow light will also glow, for 1 second each time, in between transition from Red to Green, means first red light glows for 5 second then yellow light glows for 1 second and then finally green light will be turned on. Like, at a time, there will be two Red signals on any of the two sides and one Green light on the remaining side. Here we have demonstrated Traffic lights for the 3 ways road and the code glows LED’s on all the three sides in a particular sequence, in which the actual Traffic Lights works. The code for this Arduino Traffic Light Controller Project is simple and can be easily understood. Power up the breadboard using the Arduino 5v and GND pin.Connect the other end of the wire to the Arduino Uno in the consecutive pins(2,3,4…10).Connect the connector wires accordingly.Place the negative terminal of the LEDs in common and connect the 220ohm resistor in series.Connect the LEDs in the order as Red, Green, and Yellow in the breadboard.It’s pretty simple and can be easily built on bread board as explained in below steps: The circuit Diagram for Arduino Traffic Light Controller project is given below: Here have demonstrated it for 3 sides or ways. We have covered a more simpler version of traffic lights in this traffic light circuit. This Arduino based 3-Way Traffic Light Controller is a simple Arduino DIY project which is useful to understand the working of traffic lights which we see around us. It is one of the most popular open source micro controller board which is highly useful for doing DIY projects. Keywords: IR sensor, Pilot lamp, Arduino, Traffic control.We all know about Arduino. The proposed system includes timer which runs for a specific time and IR sensor is used to count the number of vehicles passing by during that time period. The motivation for this work has been originated from the observation carried out at traffic signals located at Nizwa and Muscat cities of Oman. Hence, the density based traffic control system available at lowest expenditure will be helpful. However, the conventional hard code controlled traffic light signal which operates with a fixed time slots is found to be poor efficient since it does not consider the instantaneous traffic density. Generally, traffic police can control traffic in several junctions of cities by implementing either hard coded automatic traffic light control system or through manual intervention. Current statistics reveals that a person averagely spends around 4-6 months of his/her life time by simply waiting at traffic signal during his travel. Abstract: In recent years, road traffic has become a serious problem across the globe.
