- Buy an Arduino. Any basic model with USB HID capabilities will work (e.g., Arduino Leonardo or Micro).
- Modify your rotation addon. In the Hekili addon (or any rotation helper you prefer), edit one line of Lua code to show a specific color instead of an icon or keybind.
- Write a Python script.
It should:
- Scan a region of your screen for that color cue.
- Send a mapped signal (e.g., over serial) to the Arduino when the color is detected. - Let the Arduino handle the input.
Program it to send hardware keypresses based on the signals it receives. This mimics real keyboard input and keeps the keypresses off your PC.
Been using this in high M+ keys and Mythic raids — consistently getting 90+ parses. Zero issues so far. And you can adjust it within minutes for each game version.
If you want help getting this set up (for a small tip), feel free to DM me.
Also thinking about putting all my stuff on Github to share, if there's interest.
