About running tasks in the background: it is true that the loop() is actually a kind of ‘single task’ that does not allow (or is difficult) to run things in parallel or in the background. Use our examples to learn about mutex, semaphore and critical section code. If so, you go next state which writes tp pulseopto1 and gotes to WAIT_STATE_2 for example again setting start time to current time. The code below begins by utilizing a for loop to assign digital pins 2-7 as outputs for the 6 LEDs used. In the main loop of the code, two for loops are used to loop incrementally, stepping through the LEDs, one by one, from pin 2 to pin seven. Beide Sketche habe ich zu einem guten Stück fertig.
