The PerfectAutomatic Lighting System Using Arduino + LDR + PIR

In this project,We will set up an automatic lighting system using arduino, so the ideas came when I tried to build automatic lighting system using arduino and PIR motion sensor but I confronted big issue because the light turn ON even if daytime,this is why I thought to use LDR in order to solve this issue. The main purpose of this project is to prevent loss of current unnecessarily during day time and make the system more efficient then before. Step 1: Hardware/Software Supplies Hardware Supplies: 1. Arduino Uno ( any other arduino board will be just fine as long as it provides an Analogical pin ). 2. PIR Motion Sensor 3. LDR (Photoresistor) 4. 10 KOhms resistor 5. Relay module 6. Lamp 7. Breadboard (optional) Software Supplies: 1. Arduino IDE Step 2: Specifications of the Main Components PIR sensor: The PIR sensor stands for Passive Infrared sensor.

Amazing Control Computer Using Hand Motion and Arduino

In this project,we are going to learn how to build a technique of gesture controlled Laptops or computers,It based on using the power combination of Arduino and Python. Instead of using a keyboard, mouse or joystick, we can use our hand gestures to control certain functions of a computer like play/pause a video, move left/right in a photo slide show, scroll up/down in a web page and many more,This is why I decided to control VLC Media Player as hand gestures project. The idea behind the project is quite easy by using two Ultrasonic Sensors (HC-SR04) with arduino,We will place the two Sensors on the top of a laptop screen and calculate the distance between the hand and the sensor.Counting on the information from Arduino that is send to the python through the serial port,This information will be then read by python which is running on the computer in order to perform certain actions. Hardware components : 1. Arduino 2. Two Ultrasonic Sensors (HC-SR04) 3. So...

PIR Motion with Raspberry Pi

Introduction: Detecting Motion Using Raspberry Pi In this instructable,we are going to learn how we can use PIR ( Passive InfraRed ) Sensor with Raspberry Pi, in order to build a simple motion detector.It is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically-activated lighting systems. Operating principles: All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually this radiation isn't visible to the human eye because it radiates at infrared wavelengths, but it can be detected by electronic devices designed for such a purpose.( Source : Wikipedia ) Purpose of instructable : The main idea of this tutorial is to Turn ON Led if a motion detected, and Turn OFF Led if else.As I said in the introduction you can use the sensor to control Light Room or Alarm instead of Led. Step 1: Supplies Hardware Supplies : 1. Raspberry Pi 3 Mode...

Control Light Room With Arduino and PIR Motion Sensor

Introduction: Control Light Room With Arduino and PIR Motion Sensor Today, we will see together how you can create an Arduino PIR motion sensor for your room in order to turn ON/OFF the light by detecting human movements. PIR sensor: The PIR sensor stands for Passive Infrared sensor. It is a low cost sensor which can detect the presence of Human beings or animals. There are two important materials present in the sensor one is the pyroelectric crystal which can detect the heat signatures from a living organism (humans/animals) and the other is a Fresnel lenses which can widen the range of the sensor. Also the PIR sensor modules provide us some options to adjust the working of the sensor as shown in above image. Step 1: Supplies Pick up the supplies required : 1. Arduino Uno 2. PIR motion sensor 3. Relay module 4. Some Wires 5. Lamp Step 2: Connecting the Sensor and the Components The PIR sensor has three pins : 1. VCC 2. GND ...
