Hi there,
I have what I had hoped would be a simple project, but it hasn't worked out that way. I could really use some advice. If I have come to the wrong forum, please direct me where I should be asking this.
I am designing a simple house alarm with four door/window inputs and a chime, siren and strobe output. I threw together a PCB and I am having several problems. I have attached the schematic and code.
1st: Adafruit Huzzah Feather keeps locking up. I can only program it off of the PCB as it doesn't want to program at all on the PCB. It seems to be locking up during the main "else" statement.
2nd: I am getting weird results from the Blynk portion of the code. Maybe I am not understanding how it all works although I think I have a pretty good idea.
Please don't laugh at my code, but if you see any serious mistakes please let me know.
