Appreciate it. This will be 100% hard soldered. Breadboard just for prototyping and to help electronics noobs. I have a few relays, but no use for them yet as it’s easier to control from Home Assistant.
Having it work now, sort of. Ran into a few problems. For some reason, D2 and D3 just would not pick up the Wiegand data signals. Switching them over to D5 and D6 fixed that and wasted a frustrating amount of time.
And now the bigger problem, the data being read does not match what’s on the chip. Here’s a random magic 1k fob I have lying around according to taginfo:
UID 1A:5F:8A:96
But the Wiegand library is reversing it while keeping the HEX character in the proper order and giving me the following output:
968a5f1a
Trying a fob with a 7bit UID
04:1C:A0:3A:4C:68:80
gives me the following:
1d501c04
Going to take a lot of hammering unless someone has Wiegand coding experience.
