Build Smart Applications with Raspberry Pi, Arduino, and ESP32

Discover how easy and exciting mobile app development can be with MIT App Inventor. This hands-on guide takes you from basic concepts to building real-world mobile applications using a simple visual programming approach—no prior coding experience required. You will create IoT and AI-powered apps for Android devices and explore how App Inventor can also be used with iPhones and iPads.

Connect your applications to platforms such as Arduino UNO R4 WiFi, ESP32, Raspberry Pi Pico (2)W and Raspberry Pi 5, enabling you to build smart, connected systems.

Inside the book, you will learn how to:

• Build interactive apps using buttons, images, sound, and multimedia
• Create text-to-speech and speech-recognition applications
• Develop camera-based and location-aware (GPS) apps
• Design useful tools such as calculators and educational apps
• Work with smartphone sensors like accelerometers and light sensors
• Build AI-powered applications, including voice assistants and image-generation features
• Send and receive messages, and create communication-based apps
• Connect mobile apps to hardware using Wi-Fi and Bluetooth
• Control real devices such as LEDs, motors, and sensors

Designed for beginners, students, and hobbyists, this book focuses on learning by doing. By the end, you will have the skills and confidence to create your own innovative applications that interact with both the digital and physical worlds.
