Lab 2 - Multi LEDs

Purpose:
Make multiple LEDs blink one after the other

Equipment:
LEDs (x 4)
Resistor
Wires (x 3)
Arduino Uno
Breadboard



USB cable

Program Details:
I used the program off newinnovators.ca

Time to Program and Complete:
3 minutes

Results:
N/A

Photo/Video Proof:

Program:

int ledPin1 = 2;

int ledPin2 = 3;

int ledPin3 = 4;

int ledPin4 = 5;

//this tells the program what ledPin1, 2, 3 and 4 are equal to

void setup ()

//the code underneath is isolated from the other code

{

//anything underneath is part of the above code

  pinMode(ledPin1, OUTPUT);

  pinMode(ledPin2, OUTPUT);

  pinMode(ledPin3, OUTPUT);

  pinMode(ledPin4, OUTPUT);

//identifies the pinMode1, 2, 3 and 4 as either and output or input

}

//this is the end of the isolated code

void loop()

//the isolated code will loop forever

{

//start of the loop function

  int delayTime = 100;

//sets what delayTime is equal to

  digitalWrite(ledPin1, HIGH);

//sets the LED value to high

  delay(delayTime);

//delays the code for what delayTime is equal to

  digitalWrite(ledPin2, HIGH);

//sets the LED2 value to high

  delay(delayTime);

  digitalWrite(ledPin3, HIGH);

//sets the LED3 value to high

  delay(delayTime);

  digitalWrite(ledPin4, HIGH);

//sets the LED4 value to high

  delay(delayTime);

  digitalWrite(ledPin1, LOW);

//sets the LED1 value to low

  delay(delayTime);

  digitalWrite(ledPin2, LOW);

//sets the LED2 value to high

  delay(delayTime);

  digitalWrite(ledPin3, LOW);

//sets the LED3 value to high

  delay(delayTime);

  digitalWrite(ledPin4, LOW);

//sets the LED4 value to high

  delay(delayTime);

}

//this is the end of the loop

Program Modifications:
N/A

Helpful Tips:
Make sure the wires go to the correct ports
