Wiring Components

Let's learn how to wire components together to create electrical connections!

Step 1: Wire the Positive Side of the Battery

In the editor, you'll see a 9V battery on the left. We need to add wires to connect the battery to our circuit.

1. Hover over the red terminal of the 9V battery until you see the Positive label. Click to begin adding the wire.
2. Hover over the breadboard (the white component that all the other electronics are connected to) and click on the hole next to the "+" symbol to complete the wire.
3. Click on the wire and change the color to red in the inspector.
4. Continue to the next step.

Step 2: Wire the Negative Side of the Battery

Now we'll connect the negative side of the battery.

Instructions:

1. Hover over the black terminal of the 9V battery until you see the Negative label. Click to begin adding the wire.
2. Hover over the breadboard (the white component that all the other electronics are connected to) and click on the hole next to the "-" symbol to complete the wire.
3. Click on the wire and change the color to black in the inspector.
4. Continue to the next step.

Step 3: Start Simulation

Now that we've powered our circuit, let's test it out with the simulator!

1. Click the Start Simulation button.
2. Ensure that your computer's sound is not muted.
3. On the breadboard, you'll see 8 buttons. While the simulator is running, clicking on the button will trigger each switch. Try clicking on each of the buttons to hear what happens.
4. Continue to the next step.

Step 4: Congratulations!

Congratulations – you learned how to add wires to power a piano circuit!

Here are some pro-tips:

• When a wire is selected, you can also cycle between wire colors by typing any number on your keyboard. For example, typing 0 will give you a black wire.
• If you press the shift key and then click on a button, the button will stay pressed. Clicking again on the button will release it.
• Breadboards are a powerful tool for prototyping with electronics. If you're interested in learning more about using one, check out our tutorial on Introducing the Breadboard!
