Arduino/Raspberry Pi Projects

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...

Methods Of Detecting Water Level

In this project,I'll show you how create an inexpensive water detector using two methods : 1. Ultrasonic sensor (HC-SR04). 2. Funduino water sensor. Step 1: Using Ultrasonic Sensor As Detector The idea of ultrasonic sensor came from the bats and dolphins, they estimate distance by using the echolocation process—sound waves transmitted, bounced back and received, with the time difference used to calculate the distance of objects. First of all we need to trigger the ultrasonic sensor module to transmit signal by using arduino and then wait for receive ECHO. Arduino reads the time between triggering and Received ECHO. We know that speed of sound is around 340m/s. so we can calculate distance by using given formula: Distance= (travel time/2) * speed of sound Where speed of sound around 340 meter per second. What You Will Need ? For this project you will need: -Arduino uno -Breadboard Water -Ultrasonic Sensor -Led (optional) The C...

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...
