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 ...
