Press the button once for range 1, twice for range 2 etc. Each button press is echoed by the feedback LED. Waiting forPROGRAM_MODE_SIMPLE_END_DETECT_MILLIS(1.5 seconds) ends the programming mode and the feedback LED echoes the number of button presses recognized. The duration of signal ma...
The other problem with delay()-based timing is that user inputs like button presses tend to get ignored because the processor can't check the button state when it is in a delay(). With our millis()-based timing, the processor is free to check on button states and other inputs ...
for button presses under, between or over the set number of milliseconds. Note that all pressed of more than 2550 ms are counted as 2550 ms and the value specified here should not exceed 2550. (You can use .pressedFor(<ms>) to see if a button is held for longer.) The library provid...
