Arduino Blinking LED Tutorial

You can find the diagram and code at our website:

The code is also available on GitHub:

If you’re still having trouble, check if your wires are bad. I spent the past 2 days pulling my hair out trying to figure out why my code wasn’t working, only to find out my wires weren’t working

[murkypuddle]

This is so cool! I love how simple you can make something so that's actually so intricate. Well done tutorial! Subbed.

easy, fast, comprehensible.
feels like a babystep but hey you gotta start somewhere

[kriststreams]

4 years later the code worked but still it kinda worked

[KOCHIYEONGMoe]

#define led_pin 8


void setup() {
pinMode(led_pin, OUTPUT);

// put your setup code here, to run once:

}

void loop() {
digitalWrite(led_pin, HIGH);
delay(1500);

digitalWrite(led_pin, LOW);
delay(1500);

Thank you, look forward to the next one.

You made a lot of work on this video. Lots of respect for that 👍👍👍Question: Is the speech in your tutorial generated by software?

[joshuacox]

My led just stays on, I re typed the code 1-1 exactly like you have it on the video, and on gthub . Checked and checked the connections and everything. Changed the delay to a smaller number, and nothing the led stays solid.... HELP I just started trying to do this and I've been discouraging so many times. I do have a Ethernet shield on the Arduino but I don't think that would change anything please help, anyone lols, don't let me give up again please

[ella-mw]

its genuinely not working. i have mixed and matched different wires but no matter what i do, it just doesnt work.

[wombatZ]

Why am I not allowed to place the transistor parallel to the LED?

[juliekhov]

Does it make a difference which Arduino board you use? Having trouble deciding.

[marcjames_]

Hii how do I make the LED blink faster

[electricalengineering]

Which software you used for animation?

[devadathan]

Hi. How can I contact you? Do you have an email id? I would like to discuss something.
