So…I have this project that needs to be able to identify about 30 items and categorize them into one of two groups. Then, it needs to light up a respective set of lights for a few seconds on a physical display depending on which group it is in. My plan is to attach an RFID tag to each item and use an ID-20 to read the signal. My question, however, is this:
What other system components will I need to include so that I can light up a set of LED lights (or possibly a string of christmas lights) on the physical display? The lights need to be bright enough to be seen from the back of a classroom. Ideally, I would like to be able to do this without needing a laptop computer in the final system. Perhaps a PIC can read the serial numbers from the the ID-20 and then provide power to the desired set of lights?? Cost is not a major constraint.
Thanks in advance for your help!

You’d at least need some kind of a driver circuit for those lights. Depending on what lights you have/are going to use. You could also go for a commercial LED matrix display since money is not an issue for you.
Also instead of the PIC I’d go with an Arduino - you’ll get going faster and it already comes with a LED matrix library.

Get the RF and RFID tag reading working. Procrastinate the display- it's trivial.
Read up on RFID tag de-collision - a problem when many tags are in range simultaneously. Some standards that some tags use deal with this.
