Question

Using Arduino coding perform the following program and present flowchart

A  program that averages two arrays of N elements where N is a whole number. A temperature control process has two temperature sensors A and B. From each sensor N samples are taken and stored in a different array. You need to average the values ​​of the two sensors in another array and print it on the screen. The voltage range of the sensors ranges from 0 to 5 Volts (0 ⁰C to 100 ⁰C).

Example;

For N = 10

Array samples sensor A: 1.4 1.2 1.3 1.2 1.3 1.1 1.4 1.2 1.1 1.4

Array samples sensor B: 1.4 1.2 1.1 1.4 1.5 1.7 1.8 1.0 1.1 1.4

Array average: 1.4 1.2 1.2 1.3 1.4 1.4 1.6 1.1 1.1 1.4

Answer 1

Answer:

The program the above question is given below :

#include <OneWire.h>
#include <DallasTemperature.h>
// Data wire is plugged into pin 2 on the Arduino
#define ONE_WIRE_BUS 2
// Setup a oneWire instance to communicate with any OneWire devices
// (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);
const int numReadings = 10;
int readings[numReadings]; // the readings from the analog input
int readIndex = 0; // the index of the current reading
int total = 0; // the running total
int average = 0; // the average
void setup() {
// start serial port
Serial.begin(9600);
Serial.println("Temperatuur sensor by MAI©: 1min");
// Start up the library
sensors.begin();
for (int thisReading = 0; thisReading < numReadings; thisReading++) {
readings[thisReading] = 0;
}
}
void loop() {
// subtract the last reading:
total = total - readings[readIndex];
// read from the sensor:
readings[readIndex] = digitalRead(2);
// add the reading to the total:
total = total + readings[readIndex];
// advance to the next position in the array:
readIndex = readIndex + 1;
// if we're at the end of the array...
if (readIndex >= numReadings) {
// ...wrap around to the beginning:
readIndex = 0;
}
// calculate the average:
average = total / numReadings;
// send it to the computer as ASCII digits
Serial.println(average);
delay(1000); // delay in between reads for stability
}
