   • Use the Ethernet port for wired network connections.
   • Alternatively, connect to a Wi-Fi network using the built-in wireless module.

4. GPIO Usage:

   • Use the GPIO pins to connect sensors, LEDs, and other components.
   • Ensure proper pin configuration to avoid damage.

• Power Supply: Always use a reliable 5V/2.5A power supply to avoid power issues.
• Static Electricity: Handle the Raspberry Pi with care to avoid static electricity damage.
• Cooling: Consider using a heat sink or fan for cooling during intensive tasks.
• Software Updates: Regularly update the operating system and software to ensure security and performance.

1. No Display Output:

   • Ensure the HDMI cable is properly connected.
   • Check if the monitor is set to the correct input source.
   • Verify that the Raspberry Pi is powered on.

2. Wi-Fi Connection Problems:

   • Ensure the Wi-Fi credentials are correct.
   • Check if the Wi-Fi network is within range.
   • Restart the Raspberry Pi and the router.

3. Overheating:

   • Use a heat sink or fan to cool the Raspberry Pi.
   • Ensure proper ventilation around the device.

• Power Issues:

  • Use a reliable power supply.
  • Check the power cable for any damage.

• Software Problems:

  • Reinstall the operating system if necessary.
  • Use the dmesg command to check for system errors.

// Example code to control an LED connected to GPIO pin 17 on the Raspberry Pi
// using an Arduino UNO

// Define the pin number
const int ledPin = 17;

void setup() {
  // Initialize the GPIO pin as an output
  pinMode(ledPin, OUTPUT);
}

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

  // Turn the LED off
  digitalWrite(ledPin, LOW);
  delay(1000); // Wait for 1 second
}
