I looked at those hats and they are way too expensive and often large.

I am using this to read a thermistor, but it works like shit.

When the arduinos mini arrive i will glue one to the raspberry and read the thermistor on the arduino and them make some simple morse code type of thing where arduino sets 5V output to high and low to communicated with a GPIO pin on the raspberry
