May be you don't know how to use an ultrasonic sensor to measure the distance with an LCD display, so in this instructable I decided to make you happy and help you getting started. This sensor is very popular among the Arduino Geeks. In this project the ultrasonic sensor read and write the distance between the sensor and the object in front of it in the LCD display, It’s really simple.
My goal is to help you understand how this sensor works and then you can use this example in your own projects.
Step 1: Parts Required
Step 2: Connect the Components
Connect the components and wires as shown in this schematic.
