"WebJun 10, 2024 · We all know the way how blink without delay works. I wanted to further expand this with a function which has a few more features: void blink(int count, int ms, char color); Basically, the function should let an LED blink for 'count' times, with an 'ms' interval without interrupting / halting the loop function. Don't mind the 'color' variable here. " - Blink led without delay arduino
