Most computers require a mouse to navigate the user interface. In this project, you'll learn how you can build a mouse that connects via Bluetooth BLE and converts accelerometer readings to mouse cursor movements.

The project is built around the Adafruit Feather nRF52840 Sense. It has BLE connectivity and a lot of onboard sensors. Its accelerometer is used for sending movement data that is converted to move your mouse cursor around the screen.

Right-clicks are sent with the onboard button. Scrolling is done by covering the proximity sensor and tilting the Feather nRF52840 Sense up or down depending on the direction that you want to scroll. 

The 3D printed case features cut-outs on the top so that you can access the button and proximity sensor while keeping your board protected.
