UV Protection Amulet

Source code and KiCad design files for the UV Protection Amulet.

Uses an ATtiny84, a TTP223 Capacitive sensing chip and the VEML6075 UV sensor. The PCB thickness is 0.8mm and the battery is a CR2032 3V Lithium coin cell.

The i2c routines were modified to not require external pullup resistors.
