✡Practical Questions M4-R5 ✡
👉9 feb
Q(1)write a program to interface of fans/lights with arduino board to on/off with the delay of 1 sec.
#define LED_PIN 8
#define BUTTON_PIN 7
void setup() {
pinMode(LED_PIN, OUTPUT);
pinMode(BUTTON_PIN, INPUT);
}
void loop() {
if (digitalRead(BUTTON_PIN) == HIGH) {
digitalWrite(LED_PIN, HIGH);
}
else {
digitalWrite(LED_PIN, LOW);
}
}
Q(2) #include <SoftwareSerial.h>
int relay = 2; // Set pin for relay control
SoftwareSerial bleserial(8,9);
// setup the relay output and the bluetooth serial, and the serial monitor (if you want to print the outputs)
void setup() {
// set relay pin as output.
pinMode(relay, OUTPUT);
// start bluetooth and serial monitor
bleserial.begin(9600);
Serial.begin(9600);
}
void loop() {
if(bleserial.available()){
char char1 = bleserial.read();
Serial.println(char1);
// Set protocol that you want to turn on the light bulb, I chose 1 and 0 as on and off, respectively
if(char1=='1'){
Serial.println("ON");
digitalWrite(relay,LOW);
} else if (char1=='0'){
digitalWrite(relay,HIGH);
}
}
}
#write the program for interfacing temperature sensore(LM35) and relay such that relay is switched in when temperature increases more than 30c.
const int lm35_pin = A1; /* LM35 O/P pin */
void setup() {
Serial.begin(9600);
}
Q(3)
void loop() {
int temp_adc_val;
float temp_val;
temp_adc_val = analogRead(lm35_pin); /* Read Temperature */
temp_val = (temp_adc_val * 4.88); /* Convert adc value to equivalent voltage */
temp_val = (temp_val/10); /* LM35 gives output of 10mv/°C */
Serial.print("Temperature = ");
Serial.print(temp_val);
Serial.print(" Degree Celsius\n");
delay(1000);
}
