Interfacing L298N Motor Driver with Arduino Uno

In this tutorial we will learn how to interface L298N motror driver with Arduino Uno. You might be thinking why we need L298N for controlling a motor. The answer is very simple, Arduino board or a microcontroller IO pins don't have enough current/voltage driving capability to drive a motor. For driving the motor in both directions (clockwise and anti-clockwise) we need to use an H-Bridge. Please read our article H-Bridge - DC Motor Driving for more information. L298N is...

Interfacing Mercury Tilt Switch with Arduino Uno

In this tutorial we will learn how to interface Tilt Sensor with Arduino Uno. As the name suggests, it is an electronic device used to detect the orientation or tilting of an object and provides digital output based on the orientation. It behaves like a normal ON - OFF switch that is controlled by tilting. Tilt sensor consists of a mercury ball and two contacts in a sealed enclosure, in which the mercury ball will short the leads based...

Interfacing Servo Motor with Arduino Uno

In this tutorial we will learn how to interface servo motor with Arduino Uno. Servo Motor is an electrical linear or rotary actuator which enables precise control of linear or angular position, acceleration or velocity. Usually servo motor is a simple motor controlled by a servo mechanism, which consists of a positional sensor and a control circuit. Servo motor is commonly used in applications like robotics, testing automation, manufacturing automation, CNC machine etc. The main characteristics of servo motor...

Interfacing Ultrasonic Sensor with Arduino Uno

In this tutorial we will learn about integrating HC-SR04 ultrasonic distance sensor with Arduino Uno. Ultrasonic sensors are commonly used for obstacle detection and distance measuring applications. The sensor works on the same principles of a radar system, which converts electrical energy into acoustic waves and vice versa. The HC-SR04 ultrasonic sensor is based on the principle of SONAR, which is an abbreviation of Sound Navigation Ranging. This sensor is used in many hobby projects where there is a...
