AI Projects for the Raspberry Pi with the AI HAT+ Edge AI is transforming everyday devices by putting intelligence where it matters most: directly inside the hardware. With on-device inference, a camera can recognize a visitor instantly, a phone can translate speech without streaming audio to the cloud, and a wearable can detect anomalies in real time—fast, private, and reliable even when the network disappears. This book is your practical guide to building exactly those kinds of systems with the Raspberry Pi AI HAT+ and the Hailo-8L accelerator. You’ll start with clear foundations: core AI and machine-learning concepts, how neural networks work, and what truly distinguishes Edge AI from cloud AI—plus an honest look at ethical considerations and future impacts. Then it’s straight to hands-on physical computing. Step by step, you’ll set up Raspberry Pi OS, power and cooling, and develop in Python using the Thonny IDE. You’ll learn GPIO basics with lights and servos, mount the AI HAT+ hardware, install and verify the Hailo software stack, and connect the right camera—official modules or USB webcams, even multiple cameras. From your first pipeline to real projects, you’ll run person detection, pose estimation, segmentation, and depth estimation, then level up with YOLO object detection: smart alerts, guest counters, and custom extensions. You’ll even connect vision to motion by combining gesture recognition with servo-driven mechanisms, including a robotic arm. With troubleshooting tips, hardware essentials, and a practical Python refresher, this book turns Edge AI from buzzword into buildable reality.

Einführung in die SPS-Programmierung mit dem Open-Source-Projekt auf dem Raspberry Pi und Modbus-Beispiele mit dem Arduino Uno und ESP8266 Die SPS-Programmierung ist heute in der Industrie und in der Hausautomation sehr weit verbreitet. In diesem Buch beschreibt der Autor, wie der Raspberry Pi 4 als SPS eingesetzt werden kann. Angefangen mit der Softwareinstallation auf dem Raspberry Pi und dem SPS-Editor auf dem PC geht es nach einer Beschreibung der Hardware an das Programmieren. Es folgen interessante Beispiele nach IEC 61131-3 in den verschiedenen Programmiersprachen. Ausführlich wird auch erklärt, wie der SPS-Editor benutzt wird und wie die Programme auf den Raspberry Pi geladen und ausgeführt werden. Angefangen mit der Programmierung mit KOP (Kontaktplan) über ST (Structured Control Language) bis zu AS (Special Function Chart) werden alle IEC-Sprachen mit Beispielen behandelt. Diese können auf der Website des Autors heruntergeladen werden. Auch die Vernetzung kommt nicht zu kurz. Der Arduino Uno und der ESP8266 werden als ModbusRTU- bzw. ModbusTCP-Module programmiert, um Zugriff auf externe Peripherie zu erhalten. Damit ist es möglich, Sensoren einzulesen und Verbraucher zu schalten. Interessant dürften auch E/A-Schaltungen sein, die dem 24V-Industriestandard entsprechen. Befehlsübersichten für ST und KOP runden das Buch ab. Nach dem Durcharbeiten des Buches ist der Leser in der Lage, eigene SPS-Steuerungen mit dem Raspberry Pi zu verwirklichen.
