Air mouse is a device used to control the mouse of a device such as a computer, mobile, smart TVetc. In this project, the air mouse is made using an IndusBoard coin device.<\/p>\n\n\n\n

IndusBoard Coin has various built-in sensors such as accelerometer, magnetometer, temperature sensor etc. For the air mouse, an accelerometer is used. This sensor detects the position of the board which is implemented to make an air mouse by detecting the change in output readings.<\/p>\n\n\n\n

Additionally, left and right clicks can also be introduced by connecting the pins of the board with external buttons.<\/p>\n\n\n\n
