LESSON 3: Blink an LED With the Arduino¶
This lesson is part of a tutorial series designed to help learners think like engineers by using the Arduino R4 WiFi board. In this session, Paul Mcarter walks through building and programming a simple LED circuit to blink in an SOS pattern using the Arduino. The lesson covers a practical application of earlier tutorials and introduces basic electronic concepts such as using a breadboard, managing circuit schematics, and programming the Arduino to manipulate hardware outputs. Here’s what you will learn:
Review of Homework: The instructor reviews a homework assignment which involved blinking an LED using Arduino, building on concepts taught in earlier lessons.
Circuit Building: Detailed guidance on constructing a circuit with an LED and resistor on a breadboard, including how to connect these components to the Arduino board correctly.
Programming the Arduino: Step-by-step coding instructions in the Arduino IDE to control the LED. This includes writing digital outputs, and implementing the
pinMode
anddigitalWrite
functions.Debugging Tips: Practical advice on debugging common errors in code, such as typos or incorrect pin setups, and emphasizes the importance of checking your work and understanding error messages.
Homework Assignment: For further practice, learners are tasked to create a circuit with four LEDs that blink simultaneously, each requiring separate control through the Arduino.
