@damaru You're welcome!

@damaru Here is an ebay.ca link:

FYI, the UNI-T M830BUZ is an excellent low-cost alternative. I have been using it for at least 5 years with no problems.

@pugwash Good point, I didn't think of that.

Not my video, but I think it was the same sketch that I am using.

@etinkerer Playing the anthem of the USSR when someone enters a room. ? Won't be able to do a video though. ?

It's for a prank so I only want the Arduino to run once when the Reset pin is "de-grounded" Thanks everybody

@pugwash I was thinking 10-20 minutes for a trip-wire activated project. Thanks

Agreed.

Thanks, I'll be looking forward to it.

Thanks for the Nano comparision link. Are you going to do a video exclusively about the RPi 4 once you get yours?
