Got a schematic of the hardware it is to control?
Just made a very basic attempt at a schematic with Fritzing. (Imgur: The magic of the Internet) There's a picture in there as well of our setup until we start gutting the machine and adding in the Arduino. We are using an Adafruit Thermocouple Amplifier MAX31855 to get the temperature values and using their Library in our code.
