I need an electronic-expert, who can create a circuit and build a prototype of the following device:
It should contain a small display. On the display, I wanna show a number from 1-999. I wanna set the number on the device (with simple switch or similiar).
The device must be connected with a computer with USB.
On the computer, I have a software where I can define, at which number of device the LED should switch on.
100-200 of that device will be conncted to one computer, so I'm not sure, if USB is the best
way to connect. Maybe a differnt way is much better, or a optical connection...I need your advise for that.
Thanks for your bids.
