MetaWatch Teardown and Arduino Hookup
jimblom 
Introduction
We do have the BlueSMIRF V2 with headers and the BlueSMiRF V2 PTH version available if you are interested in using a BlueSMiRF V2 to stream UART data in your project!
The MetaWatch is a new open-source entry into the latest "Smart Watch" craze. It's a digital watch with a microprocessor and Bluetooth controller built in. It can interface with your smartphone to display stuff like weather forecasts, emails alerts, meeting notifications, or what music is playing (oh, and the time and date too).
SparkFun has a Developer's Kit of the MetaWatch in black and white, which includes the watch, a programmer/charging clip, and a license to use TI's Code Composer Studio.
The MetaWatch's standard use case is certainly very cool. Having notifications, weather, and music updates visible on your wrist is another step towards the future! But what else can we do with this hackable little device? In this tutorial, we'll go over some basics of the MetaWatch. Then we'll tear it down, and look at its guts! Then we'll put it back together and try to control it with...what else...an Arduino.
Required Materials
The Arduino portion of this tutorial will combine an Arduino board with a Bluetooth module.
- The Arduino Board can be any Arduino-compatible board -- RedBoard, Uno, Pro Mini etc.
- The BlueSMiRF Silver is used to serve as a bluetooth interface between Arduino and MetaWatch.
- You'll also need to solder wires or headers to the BlueSMiRF in order to get it connected to the Arduino.
Of course, you'll also need a MetaWatch in the style/color of your preference (White FRAME or Black FRAME).
