Challenge:  

1) I didn’t realize that I wouldn’t get wifi in my garage, which created an issue. Luckily, we have a router extender that I was able to move into the backyard. This allowed me to prototype my idea. This challenged how I consider mobility for connected devices; the connection is only as good as their network.

2) My garage door was magnetic!  This created a problem with my reed switch.  Due to this issue, I never was able to create a working prototype.  I had to hold a magnet near my reed switch in vitro to complete my proof of concept.
