Add a pushbutton switch to toggle relay - NOT Sonos #18

Closed dougstrickland closed 7 years ago

dougstrickland commented 7 years ago

I am trying to add a pushbutton switch on one of the GPIO pins, then toggle the relay between on-off states. This makes it possible to Manually turn the relay on or off with the push of a button, and not having to use Alexa every time.

I am saving the current on/off state, so simply flip it whenever the button is pushed, but I can't get the switch to be read.

Any suggestions are appreciated!

kakopappa commented 7 years ago

Push buttons often generate spurious open close singles when pressed. it's called Debounce. You have to handle it properly to get the push button working.

I like to recommend you to turn on /off a LED light with a push button first and then change the code to turn on /off relay.

Thanks for the suggestion. I've debounced the switch, and checked it with a scope. The switch is working correctly. I don't think it's getting to my code, seems to be looping through something else. Would you recommend putting it at the top of the loop script, or somewhere in the middle. I currently have it at the bottom.

I'm getting a bunch of compile errors, starting with an empty #include on line 4. I've tried working through the syntax errors, but I seem to be making it worse. Can you try compiling my script and see what you get?

Hi Doug sent you my code on email, I think pasting it in here messes it up somehow
