Designing Volume Meter (VU) Shield for Arduino: For designing VU Meter Shield for Arduino, we have used EasyEDA, in which first we have designed a Schematic and then converted that into the PCB layout ...

There are a few options to do similar things with PCB layout, including tscircuit. There’s a walk-through for using it to create an LED matrix and you can even try it out online, if you like.

The PCB layout if using a single LED array. When building this version I suggest fitting the LED bargraph last to make the board assembly easier. This board has one small link marked in red.
