Activity: _____Activity #1_________________
Title: Blinking lights
Course/Yr & Sec.: BSCS 3rd year -B2018
Subject: _ IT101-Micro Controller Programming_
Instructor: _____Prof. Edmar G. Tan___________
I. MATERIALS/COMPONENTS
1 Arduino Uno Board
1 Breadboard
Connecting Wires
II. CONNECTION DIAGRAM (Using VBB)
III. SOURCE CODE
import muvium.compatibility.arduino.*;
public class Led extends Arduino{
int ledPin[] = {9,8,7,6,5,4,3};
public void setup() {
for (int i =0;i < 7;i++)
{
pinMode(ledPin[i], OUTPUT);
}
}
public void loop() {
for (int i =0;i < 7;i++)
{
digitalWrite(ledPin[i], HIGH);
delay(1000);
digitalWrite(ledPin[i], LOW);
delay(1000);
}
}
}
IV. OBSERVATION
There are 7 leds that is used in this activity, but it only have a short code by declaring
each led in integer/character , using the for loop by this format “ for (int i =0;i < 7;i++) “ each
time the for loop will count, the led will blink after every other and will go on repeatedly each
led has 1000 millisecond turned on and off, like a blinking Christmas light.
V. CONCLUSION
The led lights will turned on and off one by one and will go on and on.
