Prep 2: Week 2 Prep
Building Circuits
The Arduino is capable of a lot of things, but it can’t do everything. To fill in the gaps we will build some circuits and connect them to the Arduino. We can then use the Arduino to control these circuits. The following videos cover what you will need to know to start building your own circuits.

Read Chapters 3, 4, and 5 in the course text.
Guide to Circuits
This guide on building circuits will go over the basics of what you need to know, including Ohm’s Law, various circuit components, and the different types of pins on your Arduino.
| Video | Description |
|---|---|
| Voltage, Current, Resistance, and Ohm’s Law | Read through this tutorial from SparkFun to learn about essential concepts for understanding circuits. |
| Resistors | This SparkFun tutorial covers a very important component: the resistor. |
| LEDs | In this tutorial from SparkFun, you’ll learn about LEDs. |
| How to: Wire an LED | In this video, Professor Siever shows you how to wire up and control an LED using the Arduino. |
| Exceptions (Review) | Exceptions are a useful tool for managing errors that may occur in your code, such as errors that result from mistakes in our circuit timings. |
