ARM Microcontrollers: Programming and Circuit Building Volume 1 is authored by Patrick Zane Hood-Daniel
Chapter 1 wasn't about code. It was about electricity as water: voltage as pressure, current as flow, resistors as narrow pipes. Chapter 2 showed him how to build a simple programming adapter using an old USB cable and three resistors—no expensive debugger needed. By Chapter 4, he understood not just how to toggle a GPIO pin, but why the internal pull-up resistor worked. By Chapter 4, he understood not just how
