Interfacing PIR Motion Sensor with Arduino

A PIR sensor is generally known to the world as a motion sensor or motion detector. So in this project we are going to use the PIR motion sensor to detect motion. Here we are going to sense movement of human by using Passive infrared sensor (PIR sensor). Using the feedback from the sensor we will control an LED with the help of Arduino Uno. Components Required Arduino Uno PIR Sensor 330Ω Resistor LED Breadboard Connecting Wires Hardware Circuit Diagram Interfacing PIR Motion Sensor with Arduino - Circuit...

Interfacing HC-SR04 Ultrasonic Distance Sensor with ATmega32 Microcontroller

Introduction This project uses an ultrasonic sensor to indicate the distance of any object from it. Here we have made a setup based on a microcontroller in which real time distance is sensed by an ultrasonic sensor and displays measured distance on an LCD display. Required Components ATmega32 Microcontroller HC-SR04 Ultrasonic Distance Sensor 16x2 LCD Display 5V Power Supply Hardware Ultrasonic Distance Locator - Block Diagram Circuit Diagram Ultrasonic Distance Measurer - Circuit Diagram Circuit Description The overall circuit assembled on the breadboard contains three major components :ATmega...

Wailing Siren using 555 Timer – Hobby Project

Today we shall talk about a really amazing circuit that produces a sound of a siren. There are different types of circuits that produce different kinds of sounds. Here is a simple circuit that produces wailing siren. The main principle of this circuit is to produce a wailing siren. The 555 timer IC is operated in astable mode. When the switch is pressed, speaker produces high pitch siren and when it is released, its pitch decreases and is switched off after...

Mobile Phone Detector Circuit

This is a very interesting hobby project which can detect active mobile phone or GSM communication in its proximity. Active mobile phone means there is some live communication is going on like calls, sms sending or receiving etc. This circuit can be used to prevent unauthorized use of mobile phones in examination halls, conference rooms etc. As you already know, today's mobile phones (2G, 2.5G, 3G, 4G, LTE) are operating in electromagnetic signals ranges from 700MHz to 3500MHz. Each countries will...
