Accelerometer Shield for D1 Mini

For all your shaky user interface needs.

I need to do some experiments with accelerometers and robots, so I decided to make this shield to make it a little bit easier for myself. It uses a LIS3DH accelerometer, which also has some “gesture” recognition built in — things like tap, double tap, shake, etc, — so the shield could also be potentially useful for ESP8266-based devices with a “physical” user interface.
