A Simple Counter Display

Post by golekupo »

Hi All,
I need advices about how to start making a simple counter display for my queue system. The counter display will be connected and controlled by my PC client via an USB port. Dimension of the counter display may be likely the same with my pc keyboard dimension. LED visibility used by counter display will be about 5-10 meters, so it will clearly enough for the customer in the queue room. So what do i need to make it? An example using: when pc (queue) client call the next (queue) number, so then the (queue) number will be shown on the counter display immediately.

Many thanks for the advices.

The first question is display:
Adafruit does sell this 5 x 2.3" alphanumeric display (as a clock):
https://www.adafruit.com/products/1198
You could use some other large 7 segment displays.
Or a "flip dot" display off a bus!
http://www.ebay.com/itm/221243936931/
Or just an standard computer LCD monitor.
You could drive that as a 2nd monitor off your PC or use a Raspberry Pi to drive it.

If you go with a USB interface, using HID will make life easier on a Windows box as you won't need a driver.
Making it a fully implemented HID Alphanumeric Display is probably not worth the bother.
I don't see a lot of direct client support for that.

You could also make it a serial interface.
This might be the easiest if the distances involved are large.

There are a few ways to go about it.
The simplest would be with a 1.2" 7-segement display with backpack: https://www.adafruit.com/products/1268
These are available in a variety of colors.
It could also be done with a matrix-panel display: https://www.adafruit.com/products/420
Or a roll-your-own 7 segment made from our 75mm bars: https://www.adafruit.com/products/1548
