Controlling Traffic Lights With Arduino Uno

Controlling Traffic Lights With Arduino Uno

Welcome to our project of building automatically controlled traffic lights.

For the full project, code, and schematics visit: http://aiversity.com/project/controlling-traffic-lights-with-arduino-uno/

Explanation of Materials:

Resistor:

A resistor is used to decrease the current power for the led. There are many types of resistors. We differentiate by their color codes.The diagram given on the right is just given for your reference.

Led

As shown in the image on the left

The long terminal which is the anode is the positive terminal of the led.

The short terminal which is the cathode is the negitive terminal of the led.

Arduino-Genuino Uno

The parts of the arduino uno are given.

The pins at the right of the board from 13 to 2 are output and input pins.

The 1 and 0 pins are the TX and RX pins

The lower pins on the left are analog input pins

The upper left pins are the 5v, GND and other pins.

BreadBoard:

The solderless breadboard is ideal for testing projects.The diagram is given:

At the bottom of the breadboard, the sides of the breadboard are connected together There are 1 positive and 1 negative rail on each side.

In each row has 5 pins connected to each other.

In this video, I have shown the function of the parts I have used in this project.
