      10 xp

Kids discover how electricity flows, build their first circuits on a breadboard and write their first Arduino programs. Every session ends with a working mini-project they can show at home. We start in the free Tinkercad simulator, then move to a real Arduino UNO.

  • Ages 8–11
  • 12 sessions × 90 minutes + final quiz
  • Level: Basic

What students will learn

  • Build safe circuits with LEDs, resistors, buttons and buzzers on a breadboard
  • Write and upload Arduino programs using setup(), loop(), delay() and if
  • Read buttons and simple sensors and react to them
  • Present a final mini-project to family and friends

Kit

Arduino UNO + USB cable, breadboard, jumper wires, 10× LEDs (red, yellow, green), 1× RGB LED, 220Ω and 10kΩ resistors, 2× push buttons, piezo buzzer, 10kΩ potentiometer, photoresistor (LDR).
