Five-key touch circuit (verified)

Overview

Input voltage: 2.4V～5.5V

Leading out the full output port, the sensitivity can be adjusted by adjusting the C1 and C2 capacitors. The larger the capacitor value, the higher the sensitivity.

Digging holes in the middle for LED display

Can be paired with: esp temperature and dimming
