The circuit is based around the "Classic" Knight Rider design ... is an LED bargraph voltmeter. So in a nutshell, the busier the drive, the more LEDs light up. Similar to the previous circuits ...

Most of us learned to design circuits with schematics ... 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 ...

This circuit uses 10 LEDs ... versions yet to be described. The PCB layout if using a single LED array. When building this version I suggest fitting the LED bargraph last to make the board ...
