Audomatic Garage Door Close

Using Arduino Project Guidance
34

Does it work?

In general in cases like this:

if (DoorCloseWarn == true) {
    Warn(); // go to the Warn function

Booleans can only be true or false, so testing for "== true" is a bit redundant. How about:

if (DoorCloseWarn) {
    Warn(); // go to the Warn function
