Tutorials

Tutorials are for doing one thing end to end. The guide explains the mental model. The reference gives exact behavior. These pages start with a visible goal and stay close to the board.

First Sketches

• Blink an LED proves that the board, serial port, and live prompt are working.

Input

• Read a Button turns a digital input into a useful boolean.
• Read a Sensor reads an analog pin and maps it into behavior.

Motion

• Fade an LED uses PWM for brightness.

Language Practice

• Build a Calculator practices named state and operations without wiring more hardware.
• Advent of Code: Safe Dial and Advent of Code: Grid Scan are small algorithm exercises.

Frothy is early. If a tutorial says a hardware surface is advanced, take that seriously: start with the LED, button, and ADC paths first.
