Introduction: LED BLINK TUTORIAL ARDUINO; THE EASIEST!!!

Lets Get Started!

IN THE VIDEO THE PROJECT HAS BEEN DONE USING JUMPER WIRES

YOU CAN DO THE PROJECT IN BOTH WAYS (WITH OR WITHOUT JUMPER WIRE) :D

CHECK THE VIDEO FOR SURE

Step 1: How It Works?LED

HEY MAKERS, LETS MAKE SOME SIMPLE PARTY LIGHTS WITH LED'S :D

-->HOW DOES IT WORK?

BASICALLY, LEDS ARE JUST TINY LIGHT BULBS THAT FIT EASILY INTO AN ELECTRICAL CIRCUIT. BUT UNLIKE ORDINARY INCANDESCENT BULBS, THEY DON'T HAVE A FILAMENT THAT WILL BURN OUT, AND THEY DON'T GET ESPECIALLY HOT. THEY ARE ILLUMINATED SOLELY BY THE MOVEMENT OF ELECTRONS IN A SEMICONDUCTOR MATERIAL, AND THEY LAST JUST AS LONG AS A STANDARD TRANSISTOR. THE LIFESPAN OF AN LED SURPASSES THE SHORT LIFE OF AN INCANDESCENT BULB BY THOUSANDS OF HOURS. TINY LEDS ARE ALREADY REPLACING THE TUBES THAT LIGHT UP LCD HDTVS TO MAKE DRAMATICALLY THINNER TELEVISIONS.

Step 2: ​WHAT WE CAN DO WITH IT?

WHAT WE CAN DO WITH IT?

>MAKE LED BLINK

>TRAFFIC LIGHTS

>BLINK GAMES

>PARTY LIGHT AND LOTS MORE.............

Step 3: Things Required

>ARDUINO UNO

>AN ORDINARY LED

Step 4: ​CIRCUIT

CONNECT ARDUINO ACCORDING TO THE CIRCUIT

> DIGITAL PIN 13- LED POSITIVE LEG

(DO NOT USE +5V OR 3.3V PIN WITHOUT 300 OHM RESISTIOR , IT CAN BURN THE LED)

> GND -LED NEGATIVE LEG

Step 5: ​CODE

CODE

OPEN THE FILE WITH ARDUINO IDE.

OR

//led blink tutorial!<br>//Get more tutorials on --> --> -->
// "MIYMAKERS"  https://miymakers.wordpress.com

void setup() {
  // '13' pin is set to be the output
  pinMode(13, OUTPUT);

}
// 'loop' makes the function run forever
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}

Step 6: DONE!

AS SOON AS YOU UPLOAD YOU CAN SEE THE LED BLINK!

>>>You can adjust the delay by changing the delay values (DELAY(1000); –> DELAY(2000); )

>>>When You Press the Reset button on Arduino it makes the led blinks 2 blinks /per Second.

Thats all makers!

I finally got the grove! Struggled getting the arduiono recognised. Now I am off and running now that I can blink a light. Now looking for ways to set up small projects for the 100s of elementary students I teach with one set to use. Traffic light and toys cars is my next project to invetigate.

Wouldn't the LED burn out without a resistor? Or is there a resistor on D13 already for the onboard LED.

You'r Correct! Theres an resistor built in!

No worries....

No there isn't, at least not that helps in this case: the resistor that's built in is in series with the built-in led only. It's not in series with an led that you attach externally. Check the schematic:

Not quite the easiest way.

Just load the Blink sketch.

The led on the Arduino will blink.

Done.
