Arduino for Hardware Prototyping is a complete, no-nonsense guide to building real electronic devices with Arduino. It skips the LED-blink tutorials and teaches the electronics, the sensors, the actuators, and the communication buses you actually need. You will learn to read the real world, drive motors and relays, log data, connect wirelessly, and turn a breadboard prototype into a finished product. Every chapter is dense with wiring, code, and the reasoning behind each design choice. By the end, you will not just blink an LED — you will build devices.
