How to Use the Component in a Circuit

Powering the Board:
- Connect the board to your computer via the USB-C port for programming and power.
- Alternatively, use the VIN pin to supply 7-12V from an external power source.
Programming the Board:
- Install the Arduino IDE (version 2.0 or later) and add the GIGA R1 WiFi board via the Board Manager.
- Select the correct board and port in the IDE, then upload your code.
Connecting Peripherals:
- Use the digital and analog pins to connect sensors, actuators, and other peripherals.
- For wireless communication, configure the Wi-Fi or Bluetooth module using the appropriate libraries.
Example Circuit:
- Connect an LED to pin D13 with a 220-ohm resistor in series.
- Use the following code to blink the LED:

// Example code to blink an LED on pin D13
void setup() {
  pinMode(13, OUTPUT); // Set pin D13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}
