Microwave Timer

 (when the timer goes off)

A microwave timer tells you if you meal is finished being heated up or not. i made my very own microwave timer ( well of course, without the microwave oven!!)using the robotics program, arduino.

To make the microwave timer, all you need are:

1. LCD SCreen
2. Jumper Wires
3. Arduino UNO board
4. Breadboard (optional)

If you want to make the microwave timer, here is your reference:

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd (0x27,16,2);
int countdown = 15;
void setup() {
// put your setup code here, to run once:
lcd.init();
lcd.backlight();
}

void loop() {
// put your main code here, to run repeatedly:
lcd.setCursor(4,0);
lcd.print(“Time Left:”);
for(int sec = countdown;sec>=0;sec–){
lcd.setCursor(6,1);
lcd.print(“00:”);
lcd.setCursor(9,1);
lcd.print(” “);
lcd.setCursor(9,1);
lcd.print(sec);
delay(1000);
}
lcd.clear();
while(true){
lcd.setCursor(5,0);
lcd.print(“Done!”);
delay(1000);
lcd.clear();
lcd.setCursor(0,0);
lcd.print(“Enjoy Your Meal”);
lcd.setCursor(3,1);
lcd.print(“Says Dawae”);
delay(1000);
lcd.clear();
}
}

Note: You have to download the LiquidCrystal_I2C library by Frank de Brabander. All you need to do is click sketch>manage library then click on LiquidCrystal_I2C library by Frank de Brabander. After you go out of the page, click on sketch again then wire.
