At Maker Faire Milwaukee this past weekend, [basement tech] was showing off his latest build, a PID controlled charcoal grill. While it hasn’t QUITE been tested yet with real food, it does w… ...

This article explains proportional integral derivative (PID) control, including the math behind it, with the use case of a linear servo motor.

Practical PID – Arduino Experiment To demo PID theory in action, I picked up an Arduino Uno from my messy drawer along with a GL5528 photoresistor (LDR) and a super bright 5mm blue LED.

But along the way he took the time to explain PID control and the choices he made during development. We see a lot of PID controllers around here, like this router based espresso machine add-on.

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...
