Sorry. Maybe if you add a delay(1000) after the digitalWrite(led, LOW)

Also there are 2 codes. You may have uploaded the wrong code.

I love seeing lit LEDs there something just hot bout em tbh 9/10 would use them again ' I'm writing with one hand

If I have a buzzer already in my circuit and I want the led to go on at the same time, how do I code that?

Here is how the adjusted code would need to look like - int led = 13; // the pin the LED is connected to int buzzer = 8 //this is 100% DEPENDENT on which digital IO pin the buzzer is connected to void setup() { pinMode(led, OUTPUT); // Declare the LED as an output pinMode(buzzer, OUTPUT); //Declare buzzer as output } void loop() { digitalWrite(led, HIGH); // Turn the LED on digitalWrite(buzzer, HIGH); //Turn the buzzer on } If there is an error in the IDE copy and paste it into a reply to this comment.

Correct code for blinking led. int led = 13; // the pin the LED is connected to void setup() { pinMode(led, OUTPUT); // Declare the LED as an output } void loop() { digitalWrite(led, HIGH); // Turn the LED on delay(1000);// Wait for 1000 milliseconds (1 second) digitalWrite(led, LOW); // Turn the LED off delay(1000);// Keep it off }

Sorry but you have to add a semicolon to it. Also, there is a delay. int led = 13; // the pin the LED is connected to void setup() { pinMode(led, OUTPUT);// Declare the LED as an output } void loop() { delay(1000); digitalWrite(led, HIGH); // Turn the LED on }

Please add semicolons after the ) in line 3 and line 7, so it will work!

My first project on this! I have never been happier to see a flashing red light before. Used the code in the comments to make it flash but the principle is still the same!

For the "Make an LED turn on and/or blink." there is a bug in the software. The LED never blinks. You might take a close look at https://www.arduino.cc/en/Tutorial-0007/BlinkingLED to identify the error in your code.
