<h3 >this project is basically about car lock and unlock with beep sound using Ir sensor and ir remote and display the action on lcd 16x2.i tried to look on internet for this project but didn't find it anywhere as a result I tried to make some thing new and done this as a college project.</h3><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/edc12321-630a-4993-9070-6af3f45e7412.jpg /><figcaption>Wiring Diagram</figcaption><img id="gallery" src=https://projects.arduinocontent.cc/a8e54b74-deef-4224-9abe-62213ed62740.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/bbd5f00c-f0d6-4728-b3f3-187c547c182c.jpg /><figcaption> </figcaption></div><figure><img src=https://projects.arduinocontent.cc/fc7ad39d-6590-4662-86de-381c36e82010.jpg /><figcaption>PCB LAYOUT</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/171932ac-6004-4453-8eed-6c8ce96daa12.jpg /><figcaption>Schematic Diagram</figcaption></figure><h3 >CODE:</h3>#include <IRremote.h>#include <LiquidCrystal.h>#define fourth_key 25979int receiver_pin = 8; int fourth_led_pin = 9;int buzzer = 10;int led[] = {0}; IRrecv receiver(receiver_pin); decode_results output;LiquidCrystal lcd(2, 3, 4, 5, 6, 7);void setup(){ lcd.begin(16, 2); pinMode(trigger, OUTPUT); pinMode(echo, INPUT); lcd.print(" CAR LOCK"); lcd.setCursor(0, 1); lcd.print(" & UNLOCK"); delay(2000); lcd.clear(); lcd.print(" MPI PROJECT"); delay(2000); pinMode(buzzer, OUTPUT); Serial.begin(9600); receiver.enableIRIn(); pinMode(fourth_led_pin, OUTPUT); }int count = 0;void loop() { lcd.clear(); if (receiver.decode(&output)) { unsigned int value = output.value; if(led[4] == 0) { digitalWrite(fourth_led_pin, LOW); tone(buzzer, 1000, 500); lcd.print("Car Lock"); delay(1000); led[4] = 1; } else { count++; if(count % 2 == 0) { digitalWrite(fourth_led_pin, HIGH); led[4] = 0; tone(buzzer, 1500, 500); lcd.print("Car Unlock"); delay(2000); } else{ digitalWrite(fourth_led_pin, HIGH); led[4] = 0; tone(buzzer, 1500, 500); lcd.print("Car lock"); delay(2000); } } digitalWrite(fourth_led_pin, LOW); led[4] = 0; Serial.println(value); lcd.clear(); receiver.resume(); } }
