Welcome to Max

This is the hardware that was sourced through a Chinese website that you probably don't have access to so I've tried to provide links with pictures below of the hardware.

1. Arduino Uno 
no for links, commonly available

2. DS18B20 temperature sensor
no need for links, commonly available

3. Screw Shield (or order directly from Adafruit, or make your own)

8. power supply,  6 vdc 3 amp

(I can't help here, its country specific. Very cheap for me about $2 in China but you need to source your own.)

Attached is some code that does not quite work well enough but probably because it was using a stepper motor instead of a servo.
We had a lot of problems with the limit switches and mostly could not accept the temperature overshoot. 

You may find something useful in the menu section.

Welcome Max ,hope you can help us with a fresh vieuw on the problem,and some nice coding.
Cheers K3
