The Arduino Uno is an open-source microcontroller development system encompassing hardware an
Integrated Development Environment (IDE) and a vast number of libraries. It is supported by an
enormous community of programmers electronic engineers enthusiasts and academics. The
libraries in particular really smooth Arduino programming and reduce programming time. What's
more the libraries greatly facilitate testing your programs since most come fully tested and
working. The Raspberry Pi 4 can be used in many applications such as audio and video media
devices. It also works in industrial controllers robotics games and in many domestic and
commercial applications. The Raspberry Pi 4 also offers Wi-Fi and Bluetooth capability which
makes it great for remote and Internet-based control and monitoring applications. This book is
about using both the Raspberry Pi 4 and the Arduino Uno in PID-based automatic control
applications. The book starts with basic theory of the control systems and feedback control.
Working and tested projects are given for controlling real-life systems using PID controllers.
The open-loop step time response tuning the PID parameters and the closed-loop time response
of the developed systems are discussed together with the block diagrams circuit diagrams PID
controller algorithms and the full program listings for both the Raspberry Pi and the Arduino
Uno. The projects given in the book aim to teach the theory and applications of PID controllers
and can be modified easily as desired for other applications. The projects given for the
Raspberry Pi 4 should work with all other models of Raspberry Pi family. The book covers the
following topics: Open-loop and closed-loop control systems Analog and digital sensors Transfer
functions and continuous-time systems First-order and second-order system time responses
Discrete-time digital systems Continuous-time PID controllers Discrete-time PID controllers
ON-OFF temperature control with Raspberry Pi and Arduino Uno PID-based temperature control with
Raspberry Pi and Arduino Uno PID-based DC motor control with Raspberry Pi and Arduino Uno
PID-based water level control with Raspberry Pi and Arduino Uno PID-based LED-LDR brightness
control with Raspberry Pi and Arduino Uno The full program listings of all the projects
discussed in the book may be downloaded free of charge from www.elektor.com 20274.
