Connect the 16×2 LCD module to the Arduino Uno as follows:.Connect the HC-SR04 ultrasonic sensor to the Arduino Uno as follows:.The module typically includes a controller that interprets the commands from the Arduino and controls the LCD’s display. It can be controlled by an Arduino microcontroller, which sends commands and data to the LCD to control what is displayed on the screen. The name “16×2” refers to the number of rows and columns on the display, meaning it has 16 columns (characters per line) and 2 rows. This system can be used in a wide variety of applications such as obstacle detection, automated door control, level detection, parking assistance, etc.Ī 16×2 Arduino LCD module is a type of liquid crystal display (LCD) that is commonly used to display text and characters. The Arduino UNO microcontroller is then used to process this distance information and display it on a convenient 16×2 LCD module. The ultrasonic sensor sends out a sound wave and measures the time it takes for the sound wave to bounce back, allowing the system to calculate the distance of the object. The HC-SR04 ultrasonic sensor distance measurement system utilizing an Arduino UNO microcontroller is a versatile and efficient solution for determining the distance of an object in front of it.
