Unfortunately the rPi only pushed 3 volts on the gpio pins and this relay needs 5V to trigger.
You will need a 5v supply, probably the same driving you pi, and then a transistor that is
turned on by t...

So, when playing around with setpoints, I find that my error integral gets wound up to a large
