Which debouncer code will work?
Posted: Thu Jul 07, 2022 5:23 pmHi All, I have seen a lot of debouncer codes available for Arduino but less that are compatible with ESP8266. I am still very new to it all which can mean that even testing these codes can be confusing. I have a sketch that sends an IFTTT notification via Webhooks when a button is pressed. I want to adjust this so that the code only runs if the button (actually a switch) is held down for 20 seconds. I have tried two approaches. One using EZButton for Arduino (may not run on esp8266?) and one using a more universal code from Danixu (original from Xoseperez). One of the things I am struggling with is how to string these example codes, and my existing code together. My original code was running entirely in Setup, but I believe we want to change that now that we are introducing the debounce function. Can anyone tell me which, if any, of these should work? I am not getting the desired results and worried it could be an error in the coding.
