Anyways, works great now and thanks for the help. If the duration is shorter than a defined time, the short press event is detected. FYI i skipped the setup function, its the same as when I made it blink. The led works with the older code (below) so I dont think its a problem with wiring. There's a minimum delay between toggles to debounce the circuit (i.e. We measure the time duration between the pressed and released events. But then I tried to tweek it so that the button would act like on on-off swtich, where you only press it once to switch between states. The sketch then increments a button push counter. If the current button state is different from the last button state and the current button state is high, then the button changed from off to on. It then compares the button's state to its state the last time through the main loop. because of a push-button press), the output pin is toggled from LOW to HIGH or HIGH to LOW. Code The sketch below continually reads the button's state. Added a delay before counter ++ also, since my switch seems to be excessively sensitive, so acts a little like a debounce function.or just a lazy way to do it. switch Each time the input pin goes from LOW to HIGH (e.g. Most of the tutorials/examples I was reading used button, so I just used that. I'm using a QT100 as the input for the switch if that makes any difference (which i don't think it should since it outputs a high (3vdc in this case) to pin 13 when touched. That said, I'm having troubles getting mine to work correctly and was wondering if someone could offer some input on the code: int counter = 1 first of all, im a web developer without experience in C, my language is php, thats why i need your help. thanks! int counter = 0 įirst wanted to say thanks for all the input on this thread as it's exactly what I was wanting to do with a mode select switch and some LED patterns. how to add delay in switch case Using Arduino Programming Questions yamaro05 October 25, 2019, 12:27am 1 good day all.
