| // DATA (yellow) = 15, PRESENT (orange) = 14, STROBE (green) = 32 | |

| // I'm using Adafruit HUZZAH32 ESP32 Feather Board, but any ESP32 should work | |
| // And the Magtek 21050071 card reader, which reads the 2nd card track only (encoded in 5 bits) | |
| // Double check your card reader, which track(s) it reads, because track #1 is encoded differently |
