Introducing the concept of electricity and electron flow — session one at iLab

Overview

Introductory STEM session covering the basics of electricity and circuits. Students went from knowing nothing to blinking an LED with their own Arduino code by the end of the session — the perfect first milestone.

Topics

What is electricity — electron flow and analogies

How circuits work — open vs closed

LEDs — what they are and how to use them safely

Basic code to blink an LED

Introduction to the Arduino UNO

Power pins and digital output pins

Activities

Slide walkthrough on electricity and circuit basics

Live Arduino + breadboard + LED demonstration

Students wired their own LED circuits on breadboards

Wrote and uploaded blink code independently

Highlights

  • Students grasped electron flow quickly using a water-pipe analogy
  • Seeing code control a physical LED was a "wow" moment for most
  • Many spontaneous questions — genuine curiosity throughout
  • All 15 students successfully blinked an LED by session end
