iam new to Arduino.
i would like to build an arduino with 3 different pid loops. its for my plastic extruder.
this is how an plastic extruder looks like http://en.wikipedia.org/wiki/File:Extruder_section.jpg
can one arduino uno control 3 different loops
i was thinking of using the i2c bus between the different components.
i need one display where i can see the 3 different setpoints and the actual temperature. witch display can do so ? or is it easier with 3 displays.
i would like to use type k thermocouples.
where do i start. i am new to arduino and have now bought my first yet :)
best regards Sten
