Sample Arduino Code

// Example code to blink an LED connected to pin 13 of the Arduino UNO
// Ensure the Arduino is powered via the 12V power supply module

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 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
}

Troubleshooting and FAQs

Common Issues Users Might Face

1. No Output Voltage:

   • Cause: Loose or incorrect wiring.
   • Solution: Verify all connections, especially the AC input terminals (L and N).

2. Overheating:

   • Cause: Insufficient ventilation or excessive load.
   • Solution: Ensure the module is installed in a well-ventilated area and reduce the load if necessary.

3. Output Voltage Fluctuations:

   • Cause: Unstable AC input or exceeding the power rating.
   • Solution: Check the AC input voltage and ensure the load does not exceed 70W.

4. Short Circuit Protection Triggered:

   • Cause: A short circuit in the connected load.
   • Solution: Inspect the load for wiring issues and resolve the short circuit.
