Getting Started:

1. Install the Arduino IDE: Download the latest version from the official Arduino website.
2. Power Up: Connect via the USB-Micro port for both power and programming or use an external 7-12V power supply if needed.
3. Upload Code: Write and upload your projects using the easy-to-use Arduino IDE.
4. Install Drivers (if needed): If your computer doesn’t recognize the board, you may need to install the CH340 driver for smooth communication.

Sample Code to Blink LED:

void setup() {
  pinMode(13, OUTPUT); // Set built-in LED pin as output
}

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

This simple example will make the built-in LED blink on and off every second, a great way to get started.

Troubleshooting:

• Board Not Recognized? You may need to install the CH340 driver for proper communication.
• Power Issues? Make sure your power source is stable and within the recommended 7-12V range.
• Upload Problems? Check that the correct board and port are selected in the Arduino IDE.
