How to make a simple PID twmperature controller

Hi everybody!

Id like to see a complete sample programme for a pid controller for controlling a cooler by the means of a digital output and an analog input (0-10v).

An "autotune" function should be included.

And yes, ive tried Google and this forum but due to my lack of experience in programming the arduino i am not even close to being able to put toghether a complete program from other peoples notes.

I really hope someone out there will bother to help me out on this one. Thanks a lot, in advance!

due to my lack of experience in programming the arduino

Start with the simple examples that come with the Arduino development software (IDE), to gain experience. There are many complete programs to read the ADC, control the intensity of an LED, etc. Then move on to other examples before starting such a complicated project.

"Autotune" is for programming professionals who understand the theory.
