    🔋 Battery: Single battery cell - provides 1.5V electrical power

    💡 LED: Two battery cells - provides 3V electrical power

    🔘 Switch: Three battery cells - provides 4.5V electrical power

    📻 Buzzer: A light that uses very little electricity

    ⚙️ Motor: Controls whether electricity can flow

    ⚡ Circuit Breadboard

    🔧 Simple Circuit: Drag components to the blue dropzones. Simple series circuit with two component positions.

    Circuit Breadboard

    Drag components here to build on the larger grid

    💡 Breadboard Tips:

    • Drag components from the palette to the blue dropzones
    • Toggle between Simple and Advanced circuit layouts
    • Simple circuit: Series connection with 2 dropzones
    • Advanced circuit: Parallel connection with 2 branches, each needing a switch and a component
    • Click switches to turn branches on/off (⚡ = on, ⭕ = off)
    • Activate the circuit to see if electricity flows!

    How to use the guided board

    1.Drag components from the palette to the blue dropzones
    2.Click switches to turn them on/off (⚡ = on, ⭕ = off)
    3.Toggle between Simple and Advanced circuit layouts
    4.Click "Activate" to see if electricity flows!

    Circuit Rules:

    • • Every circuit needs a battery for power
    • • Components must form a complete loop
    • • Open switches stop electricity flow
    • • Wires connect component edges
    • • Drag placed components to move them
