Here is the code works with devDuino v2.2
It shows how all of the sensors on board (via com port)
and also makes it possible to (expect) to download the firmware over the air. (for example through MYSController)
/*
This sketch is for a devDuino SN v2.2 with the support OTA http://www.seeedstudio.com/wiki/DevDuino_Sensor_Node_V2.2_(ATmega_328)
and MySensors 1.5
For testing all the equipment, press the button D4 when a voltage is applied.
This sketch is a modification of code written
Version 1.3 - Thomas Bowman Mørch
