Example Connection with Arduino IDE:

For this example, you will need the following:

1x ESP32-S3 Nano development board || Reference HDNPQI_ESP32-S3_NANO

Step 1 - Download Arduino IDE

Link: Arduino IDE

Before connecting the board, start by downloading Arduino IDE 1.8.x from the link above based on your preferences and operating system.

Step 2 - Configuring Arduino IDE.

First, you will need to download a set of boards in Arduino IDE. After opening Arduino, go to:

Tools -> Boards -> Boards Manager...

In the window that appears, search for "nano esp32", and the package "Arduino ESP32 Boards by Arduino" will appear in the list. Click install and wait for the installation to complete.

Next, go to "Tools" -> "Board" -> "ESP32 Arduino (Arduino)".

Select "Arduino Nano ESP32C3".

In Arduino IDE, select the newly appeared port in the Device Manager under "Tools -> Port" once the board is connected.

If you have multiple ports and are unsure which one is the ESP32-S3 Nano, press "RESET" or disconnect and reconnect the board to the USB, then check the "Ports" menu in the Device Manager to see which one appears.

Step 4 - Making connections and uploading test code

Example 1: Testing the built-in LED (Blink):

Copy the code below and upload it to the development board:

// the setup function runs once when you press reset or power the board
void setup()
{
// initialize digital pins as output.
pinMode(LED_BUILTIN, OUTPUT);
pinMode(LED_RED, OUTPUT);
pinMode(LED_GREEN, OUTPUT);
pinMode(LED_BLUE, OUTPUT);
}

// the loop function runs over and over again forever
void loop()
{
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);

digitalWrite(LED_RED, LOW);
delay(1000);
digitalWrite(LED_RED, HIGH);
delay(1000);

digitalWrite(LED_GREEN, LOW);
delay(1000);
digitalWrite(LED_GREEN, HIGH);
delay(1000);

digitalWrite(LED_BLUE, LOW);
delay(1000);
digitalWrite(LED_BLUE, HIGH);
delay(1000);
}

After uploading, the LED connected to the D13 digital pin, followed by each of the 3 LEDs in the RGB LED, will turn on and off consecutively with a delay of one second.
