Assignment 05: ELECTRONICS

Problem Statement

Combine an input and output device together and collect data for an activity connected to you. Analyze that data and make sense of it. e.g. some examples could be displaying output from temperature/RH sensor on LCD Display to find the thermal comfort in your room, sounds of different frequencies from the Buzzer as the distance computed from a proximity sensor varies, Dustbin (full vs. half vs. empty) shows LED to be RED, YELLOW, GREEN. Please documents the steps and create a video/screenshots showing the interaction between the input and the output devices. Please also upload the codes used.

Code used for Simulation in TINKERCAD

#include <'LiquidCrystal.h>
LiquidCrystal lcd = LiquidCrystal(2, 3, 4, 5, 6, 7); // Create an LCD object. Parameters: (RS, E, D4, D5, D6, D7):
const int trigPin = 11;
const int echoPin = 12;
float time, distance;
void setup()
{
lcd.begin(16, 2); // Specify the LCD's number of columns and rows. Change to (20, 4) for a 20x4 LCD
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);

}

void loop()
{
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);

time = pulseIn(echoPin, HIGH);

distance = (time*.0343)/2;

// For Serial Monitor
Serial.print("Distance:CM ");
Serial.println(distance);

// For LCD Display
lcd.setCursor(0,0);
lcd.print("Distance in CM");
lcd.setCursor(0,1);
lcd.print(distance);
