Пользовательский код устранения дребезга не работает

Это мой собственный код устранения дребезга

Он удерживает светодиод включенным, переключая необходимое пороговое значение при срабатывании после включения светодиода, чтобы поддерживать светодиод в высоком состоянии, и наоборот, при повторном срабатывании, комментарии к коду объясняют это более подробно.

/*
 * This code is my custom debounce code, I made this but this isn't working as planned, 
 * see the thing is that it turns on when I hold the button and if I release it, 
 * it starts to flickers and then gradually turn off, what is wrong with my code ? 
 * I can't see it.
