Is it possible to connect to the unused analog pins of the ATmega328?
On the hardware wiki it lists:
As unused. If I wanted to add something to those and update the sketch of the ATmega through a USB to UART, where would I solder to those analog points?
Also, would adding other sensors inline with the LCD by unplugging the jumpers and soldering together a 3-way parallel jumper wire be able to work without messing up the I2C programming that the ATmega handles for 2 seconds and that the raspberry pi takes over?
