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 ...

The dual-channel PID controller was originally meant as a humidity and temperature controller and ... to take a look at like this one built for an Arduino, and if you’re still looking for ...

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.
