README
README.md3DCapacitiveSensor
This project uses the STM32F072RB MCU on the 32F072BDISCOVERY board and a large "3D" capacitor to measure the XYZ coordinates of a user's hand in physical space so that a user can move/click a computer mouse without touching anything. This project was inspired by this video.

Questions
What parts does the 3DCapacitiveSensor use?
14 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the 3DCapacitiveSensor KiCad files?
From the Petersoj/STM32-3DCapacitiveSensor repository on GitHub, at the commit this page was made from: the board is design/3DCapacitiveSensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 3DCapacitiveSensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask Petersoj before reusing the design.
