Smart Watch

I decided to try and create a prototype smart watch that would communicate with my android phone via bluetooth.  I thought the project would be great to help me get started in android app development and further my knowledge with arduinos and low level communication protocols. In the end, the prototype looked and worked great. I have my phone app send the smart watch the time, battery remaining, and amount of new messages and the name of the newest received message’s sender via the bluetooth module. The smart watch then displays this data and reads its own battery using a lithium ion battery fuel guage. I never built it into the shape of a watch, but it had the general size and form of a watch and was a very successful proof of concept.
