7-Seg + Maxim 7219 + Pc

I need to show on the 7-seg a number that is sent from usb.

I use a Maxim to connect the 7seg to Arduino.

help :zipper_mouth_face:

What do you need help with?

If it's learning how to drive a 7 seg with the Max7219, here is a good source . . .

If it's getting input from USB, more questions need to be answered - like
Is it really USB - like from a port on the computer or the USB cable that you connect to the Arduino?

You need to throw us a bone if you need a good answer. :slight_smile:
