   • Alternatively, use the VIN pin to supply 7-12V from an external power source.

2. 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.

3. 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.

4. 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
}

• Voltage Levels: The board operates at 3.3V logic levels. Ensure connected peripherals are compatible or use level shifters.
• Wi-Fi and Bluetooth: Use the WiFi and BluetoothSerial libraries for wireless communication. Avoid using both simultaneously for optimal performance.
• Power Supply: When using power-hungry peripherals, ensure the power source can supply sufficient current.

The Arduino GIGA R1 WiFi is compatible with many Arduino UNO shields. However, ensure the shield operates at 3.3V logic levels to avoid damage.

1. The board is not detected by the Arduino IDE:

   • Ensure the correct USB driver is installed.
   • Check that the USB cable is functional and supports data transfer.
   • Verify that the correct board and port are selected in the IDE.

2. Wi-Fi or Bluetooth is not working:

   • Ensure the correct libraries (WiFi or BluetoothSerial) are included in your code.
   • Check that the board is within range of the Wi-Fi network or Bluetooth device.

3. Code upload fails:

   • Press the reset button on the board and try uploading again.
   • Ensure no other application is using the COM port.

4. Peripherals are not responding:

   • Double-check the wiring and connections.
   • Verify that the peripherals are compatible with 3.3V logic levels.
