Repost from O Level Previous paper
Very important.
M4-R5 Practical set-(2)
Q(1) Write a program to Run pattern (s) on LEDs connect at pins 3,4,5.
Pattern example
Case-1 On,on, on
Case-2 On,off,off
Case-3 Off,on,off
Case-4 Off,off,on
Case-5 Off,off,off
Answer=
//Program to Run pattern (s) on LEDs connected at pins 3,4,5
//defining LEDs
int red LED=3;
int green LED=4;
int blue LEd = 5;
int del = 1000; //Milliseconds of delay
Void Setup ()
{
// Making the LEDs outputs
PinMode (redLED, Output);
PinMode (greenLED, output);
PinMode (blueLED, Output);
}
Void loop ()
{
//Blink in pattern on,on,on
//Case-1
Serial.print("Blink in pattern");
digital Write(redLED, HIGH);
digital Write(greenLED, HIGH);
digital Write(blue LED, HIGH);
Delay (del);
// Blink in pattern on,off ,off
// Case-2
digitalWrite (redLED, HIGH);
digitalWrite (green LED, LOW);
digitalWrite (blue,LOW);
delay (del);
Note-👉(Off =LOW and On=HIGH)
// Blink in pattern off,on ,off
// Case-3
digitalWrite (redLED,LOW);
digitalWrite (green LED, HIGH);
digitalWrite (blue LED,LOW);
delay (del);
// Blink in pattern off,off,on
// Case-4
digitalWrite (redLED,LOW);
digitalWrite (greenLED, LOW);
digitalWrite (blue LED, HIGH);
delay (del);
Blink in pattern off,off,Off
// Case-5
digitalWrite (redLED,LOW);
digitalWrite (greenLED, LOW);
digitalWrite (blue LED, LOW);
delay (del);
