A first course in electronics for children. Every lesson explains one big idea with an everyday comparison and a picture, followed by a game, a hands-on build and a short quiz.

  • Level: first course, no experience needed
  • Topics: electricity, circuits, voltage/current/resistance, conductors, series & parallel, the breadboard, safety, battery, switch, resistor, LED, LDR, transistor
  • Projects: a switched LED circuit, an automatic night light, and the same circuit with a buzzer, a motor and a green LED
  • Hardware: breadboard, 2 × AA batteries, switch, resistors, LEDs, LDR, BC557 transistor, buzzer, solar motor
  • Format: 17 lessons of 20–60 minutes, each with a short quiz
  • Next course: Intro to Arduino
  • Guide: Sparky the electron, with animations in every lesson. Component photos from Wikimedia Commons (credited in each lesson).
