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

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

Troubleshooting and FAQs

Common Issues and Solutions

1. No Output Voltage:

   • Verify that the input voltage is within the specified range (6V to 24V).
   • Check all connections for proper polarity and secure contact.
   • Ensure the potentiometer is not set to the minimum output voltage.

2. Output Voltage is Unstable:

   • Check if the input power supply is stable and capable of providing sufficient current.
   • Ensure the load does not exceed the maximum output current of 2A.
   • Inspect the module for overheating and provide adequate ventilation if necessary.

3. Module Overheats:

   • Reduce the load current if it exceeds 2A.
   • Use a heatsink or active cooling to dissipate heat during high-current operation.

4. Short Circuit Protection Triggered:

   • Disconnect the load and inspect for short circuits in the connected circuit.
   • Reset the module by removing and reapplying the input power.
