A simple refrigerator door alarm made using less then $5 of parts and a Arduino. Learn to use the millis() function to add timed events to your code. Simple wiring with simple code.

I was wondering if this could be done for an "old" fridge style with the French doors and the separate freezer door (3 doors altogether). I mean not 3 switches connected consecutively but 3 separate ports/inputs to the Arduino. Please advise.
Thank you so much. It was really helpful.
Nice!
Good
Nicely done. The machine screw adjustment is "elegant."
Cool ? project
Okay okay, now let's do the whole thing McGyver style with a paperclip, some bubble gum wrap and maybe an explosion instead of an alarm 😛
Seriously though, this is like life hacks for nerds. 😉
This looks really fun and simple to do as a project! Great content! keep it up!
Which IDE you used to write the code in order to upload the program to the microcontroller? or Arduino has its own IDE?
