 Used as a basic sensor test case using the serial sensor type.
 
 I have a very old Weather Shield and it worked well enough to verify the concept of sensor data. This is here for my own reference and show casing some ideas. YMMV greatly if using this code.

 This build uses an ATTiny 2313 / 4313 for the i2c slave with an 8 pin dip switch. The status of all 8 pins on the dip switch are returned via i2c as a single byte that can be used to determine state of all 8.
 
 The main ATTiny code that reads the dip switch states and sends back a single byte with each dip's state encoded as a ```0``` for ```off``` and ```1``` for on.
