Detailed Instructions
If you are new to the Arduino Nano 33 IoT, be sure to check out our Getting Started with Arduino Nano 33 IoT tutorial. Then, follow these steps:
- Connect the components to the Arduino Nano 33 IoT board as depicted in the diagram.
- Use a USB cable to connect the Arduino Nano 33 IoT board to your computer.
- Launch the Arduino IDE on your computer.
- Select the Arduino Nano 33 IoT board.
- Select the Arduino Nano 33 IoT COM port (the number might be different).
- Enter the following code.
void setup() {
// Initialize system settings; this code runs once at startup:
Serial.begin(9600);
}
void loop() {
// Execute the main routine continuously; this code runs repeatedly:
Serial.println("Hello World!");
delay(500);
}
- Build and send your code to the Arduino Nano 33 IoT board by clicking the Upload button in the Arduino software.
- Open the Serial Monitor in the Arduino application.
- Look at the output on the Serial Monitor. It appears like this:
COM6
Hello World!
Hello World!
Hello World!
Hello World!

Modifying Arduino Nano 33 IoT Code
- Change "Hello World!" to any text you like, for example, "Hello newbiely.com".
- Build and upload the program to your Arduino Nano 33 IoT board by clicking the Upload button in the Arduino IDE.
- Look at the output on the Serial Monitor. It should appear as shown below.
COM6
Hello newbiely.com
Hello newbiely.com
Hello newbiely.com
Hello newbiely.com
