Arduino Beginner Demonstration

Overview

A brief, accessible demonstration designed for complete beginners — showing what an Arduino is, what it does, and how quickly someone with no prior experience can make something happen. The goal is not a full class but a rapid, engaging first contact with microcontroller programming.

Demonstration Sequence

1. Introduction to Arduino — what a microcontroller is and how Arduino makes it approachable
2. Blink an LED — the “Hello World” of hardware; digitalWrite and delay
3. Detect Button Input — reading a physical button; digitalRead and INPUT_PULLUP
4. Analog Input — reading a potentiometer or sensor with analogRead (0–1023)
5. Analog Output — controlling LED brightness via PWM with analogWrite
6. Controlling a Servo — rotating a servo motor with the Servo library
7. Make Some Sound — generating tones with tone() and noTone()
