Tilt Sensor

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 on...

L298N Motor Driver Module

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...
