Q-:Write a program to blink rgb led when bit

11 ,12 and 13 count one time in forward path one

time in reverse path………………..

Program int timer = 100; int ledPins[] = { 11, 12, 13, 6, 5, 3 }; int pinCount = 6; void setup() { int thisPin; for (int thisPin = 0;

thisPin < pinCount; thisPin++) {

pinMode(ledPins[thisPin], OUTPUT);

} }

void loop() { for (int thisPin = 0; thisPin <

pinCount; thisPin++) { digitalWrite(ledPins[thisPin],

HIGH); delay(timer); digitalWrite(ledPins[thisPin], LOW);

} for (int thisPin = pinCount - 1; thisPin

>= 0; thisPin--) { digitalWrite(ledPins[thisPin],

HIGH); delay(timer); digitalWrite(ledPins[thisPin],

LOW); } }

CONCEPT OF LM 35 LM 35 IS USE TO MEASURE TO

TEMPERATURE OF SYSTEM.

Write a program to measure the temperature

of classroom using lm35 and show it on serial

port……………………

Program of lm35 void setup() { Serial.begin(9600); }

void loop() { int sensorValue =

analogRead(A0);

Serial.println(sensorValue, DEC);

}

SEVEN SEGMENT DISPLAY

Q-:Write a program to show counting of 0-9 on

seven segment

// Arduino pin: 2,3,4,5,6,7,8 byte seven_seg_digits[10][7] =

{ { 1,1,1,1,1,1,0 }, // = 0 { 0,1,1,0,0,0,0 }, // = 1 { 1,1,0,1,1,0,1 }, // = 2 { 1,1,1,1,0,0,1 }, // = 3 { 0,1,1,0,0,1,1 }, // = 4 { 1,0,1,1,0,1,1 }, // = 5 { 1,0,1,1,1,1,1 }, // = 6 { 1,1,1,0,0,0,0 }, // = 7 { 1,1,1,1,1,1,1 }, // = 8 { 1,1,1,0,0,1,1 } // = 9 };

void setup() { pinMode(2, OUTPUT); pinMode(3, OUTPUT); pinMode(4, OUTPUT); pinMode(5, OUTPUT); pinMode(6, OUTPUT); pinMode(7, OUTPUT); pinMode(8, OUTPUT); pinMode(9, OUTPUT); writeDot(0); // start with the

"dot" off }

void writeDot(byte dot) { digitalWrite(9, dot); }

Void sevenSegWrite(byte digit) {

byte pin = 2; for (byte segCount = 0;

segCount < 7; ++segCount) {

digitalWrite(pin, seven_seg_digits[digit][segCount]);

++pin; } }

void loop() { for (byte count = 10;

count > 0; --count) { delay(1000);

sevenSegWrite(count - 1);

} delay(4000); }

Q-:Write a program to - Illumination of RGB LED’s with Temperature

variation using LM35………………..

program int sec1=3; int sec2=5; int sec3=6; int temp=A0; int sem; int sa; void setup() { pinMode(3, OUTPUT); pinMode(5, OUTPUT); pinMode(6, OUTPUT); }

void loop() { sa =

analogRead(temp); { analogWrite(3,sa); analogWrite(5,sa); analogWrite(6,sa); } }

Any question…………….
