This was a quick experiment to see if the parts I had lying around would make a usable thermometer.
The answer is... just about..
- Arduino Mega 2560 (any sensible arduino would do - I might port this to my Teensy 3.1 at some point)
- 4-Digit, 7 Segment Display
- 74HC595 Shift Register
- MF52 Thermistor with integrated 10K pull-up resistor
- 4x 220Ohm resistors
For the 7-segment display, I largely followed the guide here, and started out with the code therein, but modified it for my needs.

The thermistor is a simple addition, connect to the 5v and ground rails, then send the data line to A0.
I hope it's fairly self explanatory.
Works from manual testing, but it needs automated tests...
