Year 9 Electronics

Introduction to Electronics ~ The Foundation

curiosity, hands-on exploration, fun + basics.

• What electricity is: current, voltage, resistance (conceptual, not formula-heavy).

• Simple circuits (series vs parallel).

• Introduction to common components: resistors, LEDs, switches, buzzers, batteries.

• Basic safety (short circuits, polarity, safe handling of batteries).

• Reading simple circuit diagrams (symbols recognition).

• Building basic breadboard or kit-based circuits.

• Measuring with a multimeter (voltage, current, resistance).

• Soldering basics (if introduced).

1. Light & Switch Circuits

   • Build a desk lamp/night-light with LED(s) and a switch.

   • Skills: breadboarding, series/parallel, resistor basics, polarity.

   • Extension: laser-cut acrylic housing.
     
     

2. Sound & Buzzer Games

   • Make a "steady-hand wire buzzer" game.

   • Skills: circuit completion, buzzer use, basic soldering.

   • Extension: design custom game shape in Fusion 360/laser cutter.

3. Motion & Motors

   • Build a simple fan or vibrating bug-bot.

   • Skills: DC motor basics, battery packs, switches.

   • Extension: 3D print propellers/casing.
     
     

4. Mini Arduino Intro (if resources allow)

   • Blink an LED or light-sensor night light.

   • Skills: basic coding, microcontroller intro.

   • Extension: Fusion 360 design for enclosure.
