How to Make Traffic Lights Using Arduino Uno | Make Traffic Control System

Image
Introduction Vehicles moving on-road may cause unpredictable accidents leading to colossal loss of mass and life. But what is that causing the orderly movement of Vehicles? Traffic Control System. It is used to avoid accidents and to control the flow of traffic. In this project, we will be using Arduino Uno to control the timings of Led in each direction, and with this, we will guide our vehicles to move towards a particular direction. As we know, in the traffic Control System, the green led refers to move, Red is to stop, and Orange is to get ready or to slow down. We have considered Four Directions, When the Green led of Direction 1 is ON, this indicates that all the vehicles from Direction 2,3, and 4 should move towards Direction 1. Meanwhile, all the other directions i.e. those in which orange or green is not turned ON, have their red led turned ON. Afterward, Orange led of direction 2 turns ON, this indicates that all the vehicles from direction 1, 3, and 4 should get ready to m...

Measure Distance With Ultrasonic Sensor!

Image
Have you ever wondered how Obstacle Avoiding Cars work? Or How can you measure the distance of an object with a sensor? In today’s article, we bring you detailed documentation on How can you measure the distance of an object with sound waves. Moreover, you will learn to make a simple yet cool parking system in this article. Ultrasonic Sensor An ultrasonic sensor is an electronic device that measures distance by using ultrasonic waves. It is an application of SONAR (Sound Navigation and Ranging). Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception . Working of Ultrasonic Sensor One end of the Ultrasonic Sensor is a transmitter, and the other is the receiver. When we initiate the trigger pin, it emits ultrasonic waves. If there is an obstacle in the way of these waves, ultrasonic waves bounce back and diffract to the receiver end of the Ultrasonic Sensor. When these waves fall on the receiver, the echo pin initiates and ...

How Does An IR Sensor Work!

Image
 Arduino UNO is a microcontroller board- it is the brain of any electronics project. IR sensor, on the other hand, is an infrared rays transmitter and receiver. In the following project, we will learn the working principle of IR sensor followed by its application as a discriminator between black and white surfaces and as an obstacle detector with Arduino UNO. IR Sensor FC-51 IR Sensor emits and detected infrared radiations. IR radiations are part of the electromagnetic spectrum, with wavelength higher than that of visible light, and are generally invisible to the human eye. The IR sensor consists of: 1.       IR Emitter LED: Emits infrared light 2.       IR Receiver: A photodiode with resistance depending on the amount of IR light falling on it 3.       Distance Adjuster: Changes detection distance 4.       Vcc Pin: Provides 3–5 V input voltage 5.  ...
