Editing Components

Let's learn how to edit components in your circuit.

Click next to get started!

In the workplane, you'll find three blue LEDs, three resistors, and an Arduino. (Don't worry about the Arduino for now – we'll get to that soon!)

We're going to go ahead and edit the LEDs so that we have a traffic light.

Instructions

1. Click on the top-most LED. You'll see an inspector appear that lets you edit the properties of the component. Change the color of the LED to red.
2. Click and change the middle LED to yellow.
3. Click and change the bottom LED to green.
4. Continue to the next step.

Let's check that our traffic light works as expected.

Instructions

1. Click on the Start Simulation button on the top right to test out your traffic light.
2. Continue to the next step.

Your traffic lights should be blinking!

• You can also change the color of your wires. Try selecting different components in this design and see what properties you can change.
• What happens to the brightness of the LEDs when you edit the resistance of the resistor its attached to? The resistor helps reduce current in the circuit so that the LED does not exceed its maximum rated current.
• In later tutorials, you'll learn how to program an Arduino to make your designs interactive. If you want to take a peek at the code that's running your traffic lights, click the Code Editor button in the toolbar.
