Mobile phone screen auto-clicker

The simplest mobile phone clicker, combined with a control board, enables a "like" and "piano tile" game.
You can buy a PUBG-like suction cup (available on Taobao) to play; the principle of GND conduction and high-level disconnection achieves double-tap likes.
A video demonstration can be viewed on my Douyin account. The accompanying clicker control board is also open-source in my projects.
