Lab 5: External TWI Temperature Sensor

In this lab, you will add an additional external temperature sensor to the TWI interface, enabling your project to take an indoor (onboard sensor) and outdoor (external sensor) temperature.

You will need to refer to the:

• ATMega32U4 Datasheet

• Ben's Board Schematic

• AT30TS75 Datasheet

Modify your existing work to display both the on-board and external temperatures simultaneously on the LCD, e.g.

Indoor  Outdoor
   25C      10C
