By the way, we’ve covered a PID library for Arduino before. While this post talks about temperature, PID control is used for everything from flight control to levitation.

With the charcoal hot and the lid on, there are two ways to control temperature; venting to let hot air out, and blowing air on the coals to make them hotter.

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.
