Make Your Personal Air Mouse

Air mouse is a tool used to manage the mouse of a tool similar to a pc, cellular, sensible TVetc. On this challenge, the air mouse is made utilizing an IndusBoard coin machine.

IndusBoard Coin has varied built-in sensors similar to accelerometer, magnetometer, temperature sensor and so on. For the air mouse, an accelerometer is used. This sensor detects the place of the board which is carried out to make an air mouse by detecting the change in output readings.

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

Elements required:

S. no.	Title	Description	Quantity
1.	IndusBoard Coin	3cm sized dev board	1
2.	System (laptop computer)	A Laptop computer or different mouse-operated machine is required.	1
3.	USB cable	Required to attach IndusBoard to the machine.	1
4.	Push button	For left and proper click on.	2
5.	Jumper wires	To attach push buttons to the board.	3
