How to make the Control Shortcut Keys Match Board
You can create a Control Shortcut Keys Match Board working model using LED lights, wires, a 9V battery, and metal nails. Here’s how:
Materials Required:
- Cardboard sheet (for the base)
- Color paper & markers (for labeling)
- LED lights (to indicate correct matches)
- 9V battery (for power)
- Metal nails (as conductive points)
- Wires (to connect the circuit)
- Buzzer (optional) (for sound indication)
Steps to Make the Model:
1. Prepare the Base Board
- Take a large cardboard sheet.
- Divide it into two sections:
- Left Side: Write shortcut key combinations (e.g., “Ctrl + C”).
- Right Side: Write their corresponding functions (e.g., “Copy”).
2. Set Up Conductive Points
- Insert metal nails beside each shortcut key on the left.
- Insert metal nails beside each function on the right.
3. Wiring the Circuit
- Connect each shortcut key nail to its correct function nail using wires under the board.
- Attach an LED between the shortcut and function connection.
- Connect a 9V battery in series with the LED and nails.
4. User Interaction (Match Game)
- Use a metal wire probe (or another conducting object) to complete the circuit.
- When the correct key is matched with its function, the LED will light up.
- If you add a buzzer, it can also beep for correct matches.
