String numeric output with V-USB HID

Hi Ray,

Thanks for answering me on Hackster.io.

I'm a little basic in Arduino code so not all things are clear to me.

What have I done:
-I build the circuit as shown on hackster and other sites with connections at D2, D4, D5, Vcc and Gnd.
-I connect a pot to analog A0
-I uploaded the sketch to my arduino UNO.
-I disconnected my UNO from pc, and give it external Vcc.
-I connected the circuit with the USB connector
-And looks in Excel, and wait, and wait, but nothing happens...

When I connect the selfmade usb connector, my pc gives the message that there are no drivers found for this device. Also the sound you hear by connecting gives three low beeps.

If the steps as shown above are right, I have to check my circuit.

Also I have this questions:

  • We will try to use this for measurement up to 2 analog ports. Nothing else. Can I delete all unnecessarry code, p.e. all keystrokes?
  • What do you think about the velocity of this realtime connection? Measuring 50Hz lightflashing, or a 440Hz sound?

Thanks for help so far.
I hope it is useful to us. The PLX-DAQ macro for Excel is realy good too, but the disadvantage is that you have first to install the macro on your system before you can work with it.

Gr.
Johan
