Project: Gesture Controlled Mouse (Air Mouse) Using Arduino & Accelerometer

AIR Mouse is also called gesture-controlled mouse and it works based on hand gesture. In this project an accelerometer is used for measuring the tilt of hand in X and Y direction and moves the cursor according the tilt. In the project two types of circuit are used, one is the transmitter circuit and other is the receiver circuit. Transmitter circuit makes use of MPU6050 series of accelerometer, which is con ...

Arduino Calculator using 4×4 Keypad

Programming is always fun and Arduino is a wonderful platform if you are just getting started with Embedded programming. In this tutorial we will build our own calculator with Arduino. The values can be sent in through a keypad (4×4 keypad) and result can be viewed on a LCD screen (16×2 Dot-matrix). This calculator could perform simple operations like Addition, Subtraction, Multiplication and Division with ...

Rechargeable Battery Capacity Tester using arduino

Do you have a pile of AA rechargeable batteries in your drawer? Some are old, some are new, but which sets would you bring with your camera on your next trip, and which ones are past their useful life? I like using rechargeable batteries, but I’m certain that some of them are not living up to the stated capacity on the label. So how good are those batteries? Simple battery testers measure the voltage, but t ...

Simple Solar Power using arduino

Simple Solar Power Light contains energy. When light hits a conductor (or semiconductor) some of the energy is translated into moving electrons, creating current. We can harness the current using solar cells (aka photovoltaic cells). When the sun shines on a solar cell, the current output is mostly constant, which is known as direct current, DC. DC is easy to use and great for charging batteries and powerin ...

Infinity Mirror – Tony Stark Arc-Reactor thing using arduino

I'm creating a robot, but am finding that it's better if I break the build down into smaller projects. This is one of those projects, and it seems to have a look that could be used for other things as well. Step 1: Destroy a lady's compact mirror. I took the mirrors out of their plastic housing and used a dremel buffing attachment to buff the silver off the magnifying mirror. This was a horribly tedious tas ...
