Arduino Multiple LED Blink Project: LED Sequential Control Using Arduino For Beginners

Simple Arduino Tutorial about Multiple LED Sequential Control Using Arduino For Beginners.
Hi viewers! in this video i am going to show you simple arduino UNO project for beginners that is how to control multiple LED Lights and get flip flop effect by using Arduino.

Arduino Code:

In the first part of this video you will learn how to connect LED's with arduino and in the second part you will learn how to increase or decrease LED bliking delay by making changes in the above given programming code.

List Of Materials:

and some basic tools are:

int led1 = 13;
int led2 = 12;
int led3 = 11;


void setup() {
Serial.begin(9600);


// Setup the 3 pins as OUTPUT
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);


// Add "loop2" and "loop3" to scheduling.
// "loop" is always started by default.

}


// Task no.1: blink LED with 1 second delay.
void loop() {
digitalWrite(led1, HIGH);
delay (300);
digitalWrite(led2, HIGH);
delay (300);
digitalWrite(led3, HIGH);
digitalWrite(led1, HIGH);
digitalWrite(led2, HIGH);
digitalWrite(led3, HIGH);

digitalWrite(led1, LOW);
digitalWrite(led2, LOW);
digitalWrite(led3, LOW);
delay(1000);



}


// Task no.2: blink LED with 0.1 second delay.
void loop2() {
digitalWrite(led2, HIGH);
delay(100);
digitalWrite(led2, LOW);
delay(100);
}


// Task no.3: accept commands from Serial port
// '0' turns off LED
// '1' turns on LED
void loop3() {
if (Serial.available()) {
char c = Serial.read();
if (c=='0') {
digitalWrite(led3, LOW);
Serial.println("Led turned off!");
}
if (c=='1') {
digitalWrite(led3, HIGH);
Serial.println("Led turned on!");
}
}


// IMPORTANT:
// We must call 'yield' at a regular basis to pass
// control to other tasks.
yield();
}

Many thanks
I have a text file stored in sd memory as follows, it consists of three columns
0'10, 0
10, 0, 0
0, 0, 10
0, 0, 0
10, 0, 0
..
I have three LEDs connected to three terminals (pins) of the Arduino, for example 7, 8, 9

How do I get a code that enables the Arduino UNO to read the text file and convert each number 10 to 5 volts on one of the three pins
Thus, it will light three LEDs sequentially according to the data stored in the SD card memory. Thank you very much

// blinking leds

int led=13;
int led2=12;
int led3=11;

void setup() {
//initialize the digital pin as an putput
pinMode(led, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); //turn the led ON
delay(100); //wait for a second
digitalWrite(led, LOW); //turn the led off
delay(100);
{digitalWrite(led2, HIGH);
delay(100);
digitalWrite(led2, LOW);
delay(100);}
{digitalWrite(led3, HIGH);
delay(100);
digitalWrite(led3, LOW);
delay(100);}
}

where is the code. DO YOU SPEAK ENGLISH?
