atmega_sensor_module
A simple AtMega code to expose encoder readings via I2C protocol. The encoders used in the project are two encoders (YUMO E6B2-CWZ3E Rotary Encoder Quadrature) attached to robot wheels.
I2C communication allows reset of encoder readings as well as ISR counter.
This is part of a robot hobby project in which AtMega is used as a companion microcontroller to Raspberry Pi 2 for real time tasks or reading analog inputs.

TODO
- Add voltage reading to analog inputs and expose this in I2C as well. This is needed as raspberry pi 2 cannot read analog inputs. See Measuring DC Voltage using Arduino
