This hour walked you through your first Arduino project. First, we entered the sketch code into the Arduino IDE editor window, then we compiled the sketch, and finally, we uploaded the compiled sketch to the Arduino. You also saw how to use the serial monitor feature in the Arduino IDE to monitor output from your sketch. After that, you learned how to set up an external electronic circuit and interface it with your Arduino.
In the next hour, we take a closer look at the actual Arduino sketch code that we’ll be using in our projects. You’ll learn how the Arduino programming language stores and manipulates data within our sketches.
