Overview

In this lesson, students wire simple circuits to create a physical prototype using low-cost and easily-found materials.

Vocab

• Circuit - A device that provides a path for an electric current to flow, often modifying that current. In computers, circuits allow for simple logical and mathematical operations using electricity.
• Prototype - A first or early model of a product that allows you to test assumptions before developing a final version.

New Code

• pinMode(pin, mode);
• digitalWrite()
• var myLed = createLed(pin);
• var myButton = createButton(pin);
