I'm working on a project in which the hardware is already designed. The 
customer added a late stage requirement to output a numerical counter 
value. The only output port is a single three-color (RGB) LED.

Does anybody have any ideas how one might drive the LED to output a 
numerical value?

The device is a single purpose hand held grocery labeler and we want to 
count labels dispensed. The counter would not exceed 50,000 labels.

In the past, I've experimented with single LED numerical output by 
flashing the LED for each digit. The user must pay strict attention to 
the LED without blinking to count flashes accurately.  It takes practice 
to get right. I have not been able to find even a hint of possible 
methods using Google.

Thanks - JJS
