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… ...

Two PID algorithms provide predictive correction, first by analyzing the wheel motion, then feeding that data into the second which uses the IMU feedback.

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.
