How To Make Line Follower Using Three IR Sensor | Arduino Line Following Car

Image
Line Follower Cars are autonomous cars that follow a given route. We have already learned to make a Line Following Car using 2 IR sensors to follow easy tracks . Today we'll make a Line following car using Arduino and 3 IR sensors , that will precisely follow a black line over a white surface , take sharp 90 degree turns and easily follow high curvature curves . Before moving ahead, make sure you understand the Working Mechanism of IR Sensor and learn how to make 2 IR Sensor Line Follower Robot . This project is an upgrade of 2 IR Sensor Line Follower Robot.  Hardware Setup Components Required: Arduino UNO Motor Driver L298N Car Chassis (Car Frame | 2 x DC gear Motor | 2 x Tires) Jumper Cables 3 x IR Sensor  Car Assembly: The first step is to assemble the car chassis. To learn more about assembly, refer to this article:  Assemble Car Chassis . For visual demonstration refer to this video:  Assemble Car Chassis . Circuit Diagram: Software Setup Arduino needs to be programmed suc

How to Measure Temperature and Humidity with DHT Sensor

Image
DHT sensors are used to measure the humidity and temperature of the surroundings. They are widely used in IoT and Industrial applications. By the end of this article, you will be able to operate the DHT sensor with Arduino, to measure the temperature and the humidity of your environment. Required Components: 1.       Arduino Circuit Board 2.       DHT 11 or DHT 22 3.       Jumper wires Circuit Diagram DHT sensors come in two forms; ·         In form of a sensor DHT-11 Sensor DHT-22 Sensor Here we have 4 terminals, VCC, DATA, NC, GND (moving from left to right) Connections: VCC à 5V of Arduino DATA à Digital Pin 4(If you change pin number, make a change in code as well) NC à Leave Disconnected GND à Arduino GND  Note : DHT-22 sensor will have the same pin configuration as shown above. ·         In form of Module DHT-11 Module DHT-22 Module Here we have 3 terminals, GND, DATA, VCC (moving from left to right)  Connections: GND à Arduino GND DATA à Digital Pin 4

How To Make Arduino Line Following Robot | Line Follower Using Two IR Sensor

Image
Do robots that follow a specific path excite you? Guess what? We'll help you make one!  Line Follower Cars are autonomous cars that follow a given route. Today we'll make a Line following car using Arduino and IR sensor, that has its application ranging from use in industry to auto mobile application. So let's start! IR Sensor Working Mechanism IR sensor is an infrared rays transmitter and receiver. It  discriminates between black and white surfaces, returning a digital signal of Zero '0' to Arduino for white surfaces and One '1' for black surfaces.

How Does A Joystick Work? | Arduino For Beginners

Image
You have already used the joystick while playing video games or using remote-controlled cars. It is an important input device commonly used with Arduino to make projects like Joystick-controlled car . Today we'll learn how to connect the joystick to Arduino and display its position on Arduino serial monitor.  Pin Layout Joystick Module Hardware Setup Arduino GND connects to Joystick GND Arduino 5V connects to Joystick 5V Arduino Analog Input pins A0 and A2 to Joystick VRx and VRy respectively Arduino Digital I/O pin 3 to Joystick Swith pin SW Note: Arduino Analog and Digital pin connections may vary depending on your code. Software Setup Demo To see how the project works refer to the video below. We hope that you learned how to use Joystick with Arduino. Now it's time for you to make this project and share it with us. Feel free to ask any queries in the comments below. Happy Learning :)
