and an Arduino. There’s also an LCD display and a FET to control the heater. The idea behind a PID controller is that you measure the difference between the current temperature and the desired ...

At Maker Faire Milwaukee this past weekend, [basement tech] was showing off his latest build, a PID controlled charcoal ... there are two ways to control temperature; venting to let hot air ...

It is described as an “open platform” that can collect temperature from multiple sensors, apply programmable control logic, and drive different loads with a precise PID algorithm. It is built around a ...

The other innovation is the PID controller ... in temperature and pressure as the shot is pulled. The whole lot is controlled by everyone's favorite robot brain, the Arduino.
