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/UART
• Interface real sensors and actuators — BME280, MQ gas, MPU6050, motors, servos, relays
• Add local intelligence — TinyML inference, event detection, state machines
• Connect wirelessly — BLE, Wi-Fi, MQTT, dashboards
• Secure everything — secure boot, OTP keys, encrypted comms, RFID/NFC authentication
• Optimize for power — deep sleep, harvesting, supercap buffering
• Integrate it all — modular architecture, PCB design, debugging large systems

Each chapter builds toward five capstone projects that combine the concepts:

• Smart home automation that survives Wi-Fi outages
• TinyML edge AI device that detects anomalies offline
• Autonomous robot with line-following, obstacle avoidance, and gesture control
• IoT multi-sensor hub that manages a network of low-power nodes
• Solar-powered remote monitoring station that runs indefinitely

With 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.
