In this tutorial, I'll show you how to control a simple 10 LED Bar Graph display with Arduino. This type of bar graph is basically just 10 LEDs in a row with anodes on one side of the component and cathodes on the others

Step 1: Component Knowledge

Component knowledge

Let us learn about the basic features of components to use them better. LED bar graph LED bar graph is a component Integration consist of 10 LEDs. There are two rows of pins at its bottom. At the bottom of the LED bar graph, there are two rows of pins, corresponding to the positive and negative pole separately. If the LED bar graph can not work in the circuit, it was probably because the connection between positive and negative pole is wrong. Please try to reverse the LED bar graph connection. Read More

Step 2: Circuit

Let us use D3, D4, D5, D6, D7, D8, D9, D10, D11, D12 pin of Arduino UNO board to drive LED bar graph.

Step 3: Sketch

Now let us complete the sketch to control the LED bar graph.
