PetiteCaesar647 If you're using the Arduino IDE, then you should be able find the library in: tools >> manage libraries >> search for: LiquidCrystal_I2C and then install the library by Frank de Brabander.

PetiteCaesar647 The HC-SR04 is a popular ultrasonic distance sensor. The sensor transmits high frequency ultrasonic sound which bounces off nearby objects. The sensor then listens for the echo, the difference in time from when the sound is transmitted and received, can be used to calculate the distance to an object within about 4 meters infront of the sensor.
