PIR sensors are used to detect motion. when a human or animal will get in the range of the sensor it will detect a movement because the human or animal body emits heat energy in a form of infrared radiation. The HC-SR501 sensor is an easy-to-use PIR sensor that can be used with Arduino. In this article, learn about HC SR501 PIR Sensor, how it works and how to interface it with the Arduino Board for detecting motion. This article covers Pinout, Schematic, Arduino Code standalone use. playwithcircuit.com/how-hc-sr501-pir-sensor-works-how-to-...
In this tutorial you will learn how a stepper motor works, types of stepper motors, and how to control a stepper motor using a ULN2003 driver and an Arduino UNO board using different modes of operation.
The HC-SR04 used for measuring distances in electronic projects.This module utilizes ultrasonic sound waves to determine the distance between the sensor and an object. Interfacing the HC-SR04 ultrasonic sensor with an Arduino is a common project for measuring distance. In this blog, we will explore about ultrasonic sensor, including how they work and how to interface it with Arduino.
