These scripts should work but may be buggy since I'll be maintaining the app instead.

Creating a combination dial lock with a rotary encoder in QMK

Below is a snippet for implementing a combination dial-like mechanism you can use in your QMK keymap. This is useful for entering long passwords using a rotary encoder, or activating secret macros etc. The algorithm looks for a sequence of clockwise (CW) or counter-clockwise (CCW) turns of the rotary encoder for a certain number of ticks/clicks. It executes the macro if all turns are successfully completed, or resets to the beginning if a turn is too long or too short.

For this example we will output a string as a macro, like entering a password. In this case it is "TA DA!":

void emit_passphrase_secret(void) {
