Arduino Tutorial - LED Blink / Code Included

Tutorial on making LEDs blink using Arduino microcontroller platform. Any resistor between 220 and 1000 Ohms should work fine. Very easy demo for beginners. Link to code below. Look out for more videos to come!

Hi folks, any resistor value from 220 Ohms to 1 kiloOhms would suffice.

awesome work,
this was my 1st ever time working with this stuff and i saw this vid, watched it and it worked :D good job :D

[mariuspetcu]

THANK YOU too. Believe me when I say : I was watching more then 100 videos, but none of them so exquisit explaned . Maan You have a gift . Use it !!!. 
I need Your help to make these project :how to make an led blink to reproduce S.O.S. morse code " " and ALONG with him IN THE SAME TIME a buzzer to reproduce the same code but in sounds "
I need badly these code for a Modeling Project colled " Lost Model Submarine "
- can I use a LASER DIODE instead of an LED (Recovered from a pointer pen)?.
THANK YOU again . 
All the Best . 
Please don't forget me !.

Awesome dude, reading over instructions several times, I'm just not a reader, after hearing it explained by you, made it tons easier. I now have a mini disco for ants going on! yeeow!

I will be highly obliged if any body guide me in blinking a LED with different ON and OFF duration, without using delay function.

[GoobNoob]

Thank you. There is no other tutorials out there like this. I have not found any that just tell you what you need to know. Alway's over complicated. Thank You.

[tchiksguitars]

this was awesome, thank you ! That was my first arduino project:)

[prateeklende]

it solved my very easy doubt. very easy to follow, helped a lot :)

[bcstudios]

this helped me a lot my friends thought it was cool and I was a wizard so thanks 😉😉

With a little bit of added production value you would be huge on YouTube.
Great job not only explaining the "what" but also the often overlooked "why" when doing something.
Hope to see you creating more content in the future.

Thank you.

just a tip to everyone who may have problems uploading sketch, make sure your com port is correct, this fixed my problems

Hello sir cani use 230v 5w bulb with single relay module... same code???

[ema]

It helped alot. Though my green flashed before yours .... Thank you

[FrancoisGasnier]

Thank you so much for publishing this. This was my first 'project' with the arduino kit I received this morning.
I just hesitated as far as the resistor to pick. There are four types in my kit and while watching the video, I was unsure as far as the value you used in the video.

[peterschuitemaker]

Thank you for this video, very well explained. The provided circuit for a 2 led alternating exercise wasn't working, but yours does. Saved our day!

Sketch uses 924 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Thank you very much! I am very new to the Arduino and love the potential for personal projects. Not "taking over the world, mind you", ...but things like controlling LED's and servos's and stuff. I like the fact that you spoke at a moderate pace and that you actually SHOWED which inserts to make on the breadboard. Keep up the great work, sir!
