How can I debug my Arduino code effectively?
You can start by using the Serial Monitor to print debug messages. What specific issues are you facing?
My LED isn't turning on when I expect it to. I've checked the wiring.
Make sure your code includes the correct pin mode and that you're sending the right signal. Can you share your code?
Sure, here's my code:
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}
Your code looks good. Have you tried using a different LED or checking the power supply?
