Led Bar Graph Display - Uctronics Ultimate Starter Kit for Arduino Manual

Overview
In this lesson, you will learn how to control a LED bar graph in a row
Components Required
Name
UNO R3 or MEGA 2560
220Ω Resistor
Breadboard
Component Introduction
The bar graph is made of 10 independent LEDs in a row. Internal
schematic diagram for the LED bar graph shows in the right
picture. In this lesson, we will use a potentiometer to change
the input voltage of an analog pin. Then Arduino read the
voltage and display the voltage level on the LED bar display.
