1. Powering the Board: Connect the board to your computer via a USB cable or supply power through the VIN pin.
2. Connecting I/O: Utilize the digital and analog pins to interface with sensors, actuators, and other components.
3. Programming: Use the Arduino IDE or other supported development environments to write and upload code to the board.

• Always ensure that the power supply is within the specified range to prevent damage.
• When connecting external components, make sure they are compatible with the 3.3V logic level.
• Avoid drawing more than 10mA from any I/O pin.
• Use the onboard LED (usually connected to pin 13) for simple debugging.
• For Bluetooth applications, ensure compliance with BLE protocols and standards.

• Board not recognized by the computer: Check the USB cable and drivers.
• Failure to upload code: Ensure the correct board and port are selected in the IDE.
• Unexpected behavior in circuits: Verify connections and power supply voltages.

• Use a different USB port or cable if the board is not recognized.
• Double-check the board selection in your development environment.
• Ensure that all external components are correctly connected and powered.
• Consult the board's schematic and datasheet for detailed information.

Q: Can I use the Arduino IDE with the RedBoard Artemis? A: Yes, the RedBoard Artemis is compatible with the Arduino IDE.

Q: What is the maximum voltage that can be applied to the I/O pins? A: The maximum voltage for the I/O pins is 3.3V.

Q: Does the RedBoard Artemis support battery operation? A: Yes, it can be powered by a battery connected to the VIN pin.

Q: How do I enable Bluetooth functionality? A: Bluetooth can be enabled through the appropriate libraries and code within the Arduino IDE or other development environments.

Below is a simple example of how to blink the onboard LED using the Arduino IDE:

// Define the LED pin
const int ledPin = 13;

// The setup function runs once when you press reset or power the board
void setup() {
  // Initialize the LED pin as an output
  pinMode(ledPin, OUTPUT);
}

// The loop function runs over and over again forever
void loop() {
  digitalWrite(ledPin, HIGH);   // Turn the LED on
  delay(1000);                  // Wait for a second
  digitalWrite(ledPin, LOW);    // Turn the LED off
  delay(1000);                  // Wait for a second
}

Remember to select the appropriate board from the Tools menu in the Arduino IDE before uploading the code.
