Hello all, I've been searching for hours trying to figure this out between this forum and the internet. I've found I don't even know what I'm searching for because I can't find anything related.
I'd like to figure out how to make a detector that will sound an alarm when I'm too far from my son. Scenario: My son is in his stroller with some device (one of the things I want to build). If I were to walk away for some silly reason and get more than 10 feet away, I'd have a key fob or some other device in my pocket that would alarm to remind to go back and get my son.
Can anyone point me in a direction of what I should be looking for? I've youtubed like crazy key fobs but I don't think that's what I need. I'm just not sure what that is. Any suggestions?
Thank you.
Mike
