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.

A temperature sensor monitors the room temperature from afar, and a solid-state relay (SSR) controls the power for the heater. Now he just needed a PID library — readily available from Arduino ...

The dual-channel PID controller was originally meant as a humidity and temperature controller and was based on existing software for an ATmega328.
