A fun little mouse that doesn't need an optical sensor! The wand has two physical buttons to act as left and right mouse buttons. A gyroscope acts as a scroll controller, scrolling up and down based on the tilt of the wand. An accelerometer detects the movement of the wand, allowing it to be used as a mouse pointer. An ESP32S3 powers the wand, and it connects to a computer via Bluetooth HID.
Two main reasons:
- I teach codding and math classes every week, and I'd love to write on a digital whiteboard. Unfortunately, I find drawing with my current mouse hard. I think the Wand is smaller, so it should be nicer to hold (it's like a very very chunky pencil). I think it would also be cool to be able to draw in midair so I can write on the whiteboard while walking around the classroom.
- I work on a very glossy table sometimes and my optical mouse doesn't work well on it. The Wandd should solve this problem, since it's based on motion only.
Note: Despite what the wiring diagram says, the Wand plans to use a 420mAh battery
