This is a simple project to test my 8266Wing shield. I will also use it as an example to demonstrate how to use the shield.

It uses a thermistor to measure the temperature in a freezer it then uploads the temperature to ThingSpeak. It also turns on a buzzer if the temperature is above -18°C.

In the unlikely case that you find the temperature of my freezer to be interesting, you can follow it here: Freezer temperature on ThingSpeak

I will upload source code and schemetics as soon as I have released the library and cleaned up the example a bit.
