i2c_dip
A simple i2c based dip switch that can be queried as a sensor.
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.
