Trying to setup a garage door opener with a physical sensor and an LCD screen on my app. There’s a youtube video of a guy who did this with a feather huzzah. I’m trying to do this with a raspberry pi.
I don’t believe this code he has will work directly with the Raspberry Pi (see below). Can someone clarify that? Is there anyone that could convert this to something I could run on the Raspberry Pi? Thanks for any help/advice.
#include <Blynk.h>
/*************************************************************
This is the latest and likely final rev of my Smartphone Garage Door Opener sketch
using the Adafruit Feather Huzzah board and the Blynk framework. It's pretty robust
and yells at you when you leave the garage door open too long. I hope it serves you well.
