How to End a Loop instantly

One quick and dirty option is to write a 'myDelay()' function that checks the button while waiting for time to expire. If the button is pressed, have it return 'true'. If the time expires, have it reurn 'false'. Then, in your code, replace "delay(100);" with if (myDelay(100)) return; The 'return;' statement will exit from loop() which will then be called again and will detect that the button is pressed. bool myDelay(unsigned long delayTime) { unsigned long startTime = millis(); whi…

I think this, possibly expanded with setjmp/longjmp might be another inelegant but workable kludge.

But sooner later take @paulpaulson's advice. Once you get the hang of it, you'll be empowered by the technique, and it actually makes for much more readable as well as flexible code.
