Embedded Systems with Raspberry Pi Pico 2 and RP2350: Projects, TinyML, and IoT Applications

From the first GPIO blink to fully autonomous, secure, low-power, edge-intelligent systems that run for years on harvested energy.This is not another beginner tutorial collection or dry academic textbook. It is a complete, battle-tested progression written by someone who has built, broken, and deployed these exact systems in the real world.I walk you through every step as if we're sitting together at the workbench:Master the RP2350 hardware — GPIO, ADC, PWM, PIO, I²C/SPI/UARTInterface real sensors and actuators — BME280, MQ gas, MPU6050, motors, servos, relaysAdd local intelligence — TinyML inference, event detection, state machinesConnect wirelessly — BLE, Wi-Fi, MQTT, dashboardsSecure everything — secure boot, OTP keys, encrypted comms, RFID/NFC authenticationOptimize for power — deep sleep, harvesting, supercap bufferingIntegrate it all — modular architecture, PCB design, debugging large systemsEach chapter builds toward five capstone projects that combine the concepts:Smart home automation that survives Wi-Fi outagesTinyML edge AI device that detects anomalies offlineAutonomous robot with line-following, obstacle avoidance, and gesture controlIoT multi-sensor hub that manages a network of low-power nodesSolar-powered remote monitoring station that runs indefinitelyWith clear code snippets, wiring diagrams, troubleshooting checklists, hardware/software references, and honest accounts of what broke and how I fixed it, this book equips you to design reliable, production-grade embedded systems — not just prototypes.Whether you're a student, hobbyist, engineer, or professional, if you want to go from blinking an LED to building secure, intelligent, long-lived IoT devices, this is the guide I've always wished existed.Build boldly. Measure carefully. Make it last. Read more
