Let's build an exciting project by combining an Ultrasonic Sensor with a 16x2 LCD character display to build an electronic distance measurement device. We will use one of the most easily available 9-volt batteries for powering this standalone device prototype.
For building the distance measurement device, the following parts will be required.
- Arduino Uno R3
- USB connector
- 1 pc. 9 volt battery
- 1 full sized bread board
- 1 HC-SR04 ultrasonic sensor
- 1 pc. 16x2 LCD character display
- 1 pc. 10K potentiometer
- 2 pcs. 220 ohms resistor
- 1 pc. 150 ohms resistor
- Some jumper wires
Before we start building the device, let's understand what the device will do and the various parts involved in the device. The purpose of the device will be to be able to measure the distance of an object from the device. The following diagram depicts the overview...
