Hello,
Today I wanted to program my Arduino Uno to make use of the LED blink sketch that is included in the examples.
When I upload the sketch i get no errors but the LED doesn't blink.
I've tried these things but with no success:
- Replace the LED
- Replace the 220 Ohm resistor
- Replace the jumper cables
- Replace the Arduino Uno
- Replace the USB cable
- Use another breadboard
- Tried to use an Arduino Mega instead of an Arduino Uno but gives the same issue
- Reinstalled and updated the Arduino IDE
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(10, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(10, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(10, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
I've never had this issue before and it's really holding me back to do anything with the Arduino if I can't even make an external LED blink.
If anyone could help me with this problem, thank you very much 
.
