Let's design an RFID reader without specialized ICs
Details
RFID doesn't take incredibly complex circuits if you aren't demanding great range. We'll see if we can design a low parts count 125kHz RFID reader and connect it to an Arduino.
I could use some help with the programming. I have some example code from a few places. Familiarity with decoding Manchester encoding would be useful, but not required.
We'll be focusing on 125kHz EM4100 compatible tags.
