Lets On/OFF LED using Arduino Programming and Circuit | Basic To Advanced Languages | Arduino Lesson Part 2

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.

Lets Blink LED using Arduino | Basic To Advanced Languages | Arduino Circuit and Programming | IOT | Arduino Tutorials Lessons | Part 1

LED Blinking using Arduino Circuit and Programming We will create a program for LED light blinking using Arduino Uno, first We'll discuss about LED Light Blinking of programming and then we'll put/insert LED light to the Arduino Uno Circuit in last we'll see LED light of blinking of OUTPUT. The Code: int ledpin = 13; void setup() { // put your setup code here, to run once: pinMode(ledpin , OUTPUT); } void loop() { // put your main code here, to run repeatedly: digitalWrite( ledpin, HIGH); delay(1000); digitalWrite( ledpin, LOW); delay(1000); } OR If you directly want to use the pin number instead of variables void setup() { // put your setup code here, to run once: pinMode(13 , OUTPUT); } void loop() { // put your main code here, to run repeatedly: digitalWrite( 13, HIGH); delay(1000); digitalWrite( 13, LOW); delay(1000); }

On Off LEDs using Arduino Programming Breadboard Circuit LEDs and Resistors | Basic To Advanced Languages | Arduino Tutorials Lessons | Part 3

  ON/OFF LEDS using Arduino Programming, Circuit, LEDs and Resistors. In This Video, we'll discuss Arduino programming, Breadboard LEDs Resistors and Circuit How to On Off multiple LEDs. Use Resistors with LEDs, if you don't use your Arduino circuit maybe damage. because we on off LEDs there's a particular current therefore. You should have these to performing this basic task. Arduino IDE. Arduino Uno/ smd r3. 4 LEDs. 4 10K Resistors. Breadboard. I've not used Resistors just to show you output, in up coming course will learn the usage. The Code for you to Perform: int pin1=12; int pin2=10; int pin3=7; int pin4=3; void setup() { // put your setup code here, to run once: Serial.begin(9600); pinMode(pin1, OUTPUT); pinMode(pin2, OUTPUT); pinMode(pin3, OUTPUT); pinMode(pin4, OUTPUT); } void loop() { // put your main code here, to run repeatedly: if(Serial.available()) // if there is digital pin as output { String comma...
