An IoT Button using an Adafruit Huzzah or Sparkfun Thing, a push button and the IFTTT Maker Channel (or any other http endpoint). Posts JSON data to an IFTTT Maker Channel event when the button is pressed.

I soldered male pins on my Huzzah, and added female headers to my Sparkfun Thing. The thing did not come with any headers and male headers were included with the Huzzah.

I was able to program both with my [FTDI Friend](https://www.adafruit.com/product/284), you will need to cut the default RTS jumper on the back of the FTDI Friend (used by the Huzzah) and connect the DTR jumper to program the thing. If you have both boards once cut it has been pretty easy to switch back and forth by soldering the jumpers as needed.

I still need to write some sleep code to be more efficient on battery use.
