Make Your Personal Air Mouse

Air mouse is a tool used to regulate the mouse of a tool comparable to a pc, cellular, good TVetc. On this mission, the air mouse is made utilizing an IndusBoard coin gadget.

IndusBoard Coin has numerous built-in sensors comparable to accelerometer, magnetometer, temperature sensor and so forth. For the air mouse, an accelerometer is used. This sensor detects the place of the board which is applied to make an air mouse by detecting the change in output readings.

Moreover, left and proper clicks can be launched by connecting the pins of the board with exterior buttons.
