The Arduino controls the belt speed and runs PID loops which control heating elements in each of the oven’s 3 zones.

A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...

[Matt] wanted to have more control over his meat smoker so he built this advanced PID smoker controller. It uses the solid state relay seen in the bottom-right of this image to switch the smoker’s ...

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 ...

New Book Release The new book, PID-Based Practical Digital Control with Raspberry Pi and Arduino Uno , is about using the Raspberry Pi 4 and Arduino Uno in PID-based automatic control applications.

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

The system here monitors temperature, humidity, and smoke levels and alerts you if those levels reach a certain point.
