Lesson 8 Serial Monitor
Introduction
In this experiment, you will learn how to turn on or off LEDs through a computer and the Serial Monitor. Serial Monitor is used for communication between the Uno board and a computer or other devices. It is a built-in software in the Arduino environment and you can click the button on the upper right corner to open it. You can send and receive data via the serial port on the Uno board and control the board by input from the keyboard.
In this experiment, since we use colored LEDs as loads, you can enter a color among red, green, and blue on Serial Monitor in the IDE. The corresponding LED on the Arduino Uno board will then light up.
Components

1 * Arduino Uno board
1 * Breadboard
3 * LED
3 * Resistor (220Ω)
Jumper wires
1 * USB cable
Principle
Here, the Serial Monitor serves as a transfer station for communication between your computer and the Arduino Uno board. First, the computer transfers data to the Serial Monitor, and then the data is read by the Arduino Uno board. Finally, the Uno will perform related operations.
Experimental Procedures
Step 1: Build the circuit

The schematic diagram

Step 2: Program (Please refer to the example code)
Step 3: Compile the code
Step 4: Upload the sketch to the Arduino Uno board
Now, click the Serial Monitor button at the upper right corner in the IDE. Then the Serial Monitor window will pop up as shown below.

With this window, you can not only send data from your computer to the Arduino Uno board, but also receive data from the board and display it on the screen. When you open the window, it will display “Please input any color of LED:”. You can input a color here. If you enter red, green, or blue, click Send, then the corresponding LED on the breadboard will light up. However, if you enter any color other than these three, no LEDs will be on.
For example, if you input red, you will see the red LED light up.
