WebStep 3: A Function Usable by Any Led. And here is the final code with a second led. the only var to declare outside the function is the array, that stores the millis value for each of the led you want to use. So when you … WebThe Arduino loop() function makes the use of a while loop redundant in this case. Even worse: the way you've implemented that while loop prevents buttonState from being updated, thus getting stuck in the loop. What you actually need is to use timers to blink the LED, and a 2-state machine driven by HIGH to LOW button transitions. Try this instead:

WebDec 26, 2015 · When you do delay (1000) your Arduino stops on that line for 1 second. delay () is a blocking function. Blocking functions prevent a program from doing anything else until that particular task has completed. If you need multiple tasks to occur at the same time, you simply cannot use delay (). If your application requires that you constantly ... WebDec 31, 2024 · 2. Look at my answer to a similar question. Apply the same principle to your problem: Move each task (blinking; calculating RPM) into its own separate function. Make loop () call those functions as often as possible. Make each function decide whether it is time to do its task, do it or not, and return. Those functions must never wait. the shiny shrimps film
