Lets ON/OFF LED Using Arduino Circuit and Programming.

In this Videos we'll discuss Controlling Led On/Off Arduino Programming in detail, then we will plug/insert Led into the Arduino Circuit in last we will perform Outputs.

Performing this basic task you should have a Arduino IDE on your PC or Laptop for write Arduino code to on/off LED.

These things you must have:

Arduino IDE.

Arduino Code which is given bellow.

Arduino Uno / smd r3.

10K resistor.

LED.

The code for you to test.

void setup() {

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

Serial.begin(9600); // set baud rate speed of communication

pinMode(13, OUTPUT ); // led of output function

} void loop() {
// put your main code here, to run repeatedly:

{

if(Serial.available()) // if there is digital pin as output

{

String command = Serial.readStringUntil ('\n'); // read String Until Meet newline character

if( command == "ON") {

digitalWrite(13, HIGH); // turn on LED

Serial.println("LED is Turn ON"); // send action to Serial Monitor

}

else if ( command =="OFF")

{
digitalWrite(13, LOW ); // TURN OFF LED

Serial.println("LED is Turned OFF"); // send action to Serial Monitor

}
}
}
}

OR

int ledpin = 13;

void setup() {

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

Serial.begin(9600); // set baud rate speed of communication

pinMode(ledpin, OUTPUT ); // led of output function

} void loop() {
// put your main code here, to run repeatedly:

{

if(Serial.available()) // if there is digital pin as output

{

String command = Serial.readStringUntil ('\n'); // read String Until Meet newline character

if( command == "ON") {

digitalWrite(ledpin, HIGH); // turn on LED

Serial.println("LED is Turn ON"); // send action to Serial Monitor

}

else if ( command =="OFF")

{
digitalWrite(ledpin, LOW ); // TURN OFF LED

Serial.println("LED is Turned OFF"); // send action to Serial Monitor

}
}
}
}

and verity and upload it to Arduino IDE and perform basic task. if you wanna learn each and every step then watch till end this videos.
