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 ...

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 selection of a suitable controller involves analyzing the whole temperature control system, as well as the controller. There are three types of controllers: PID, proportional, and on-off. The type ...

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.

I made this project because I wanted a way to automatically control the speed of a DC fan ... RC filter at the output of the PWM pin on the Arduino board. I used an LCD shield to display the current ...
