The bar graph - a series of LEDs in a line, such as you see on an audio display - is a common hardware display for analog sensors. It's made up of a series of LEDs in a row, an analog input like a potentiometer, and a little code in between. You can buy multi-LED bar graph displays fairly cheaply, like this one.

Arduino LED Bar Graph - Learn how to create an LED bar graph using Arduino. This tutorial covers components, wiring, and programming for a successful project.

The bargraph display is connected to the Arduino (2,3,4,5,6,7,8,9,10,11) digital IO pins through 330 ohm current limiting resistors. The potentiometer is connected to the Arduino ADC (A0) pin for simulating the signal strength. The potential read by the 10 bit ADC, (1024 steps ) is mapped to 0 to 10 scale and correspondingly activating the LED’s at the Bargraph display in increasing order ...
