Hello, this is my first experimentation after doing blinkie.
I purchased a RFID reader from ebay a while back, it was $10 and came with 2 rfids and does not require a computer.
I have played wired it up to an led and have played with it getting it to turn on when the right rfid is shown. Basically if I show the right card, the led lights up, when I take the card down, it immediately shuts off, so there is no relay.
Can I hook this into Arduino? It is a 12v signal that comes out of the rfid.
Meaning, can I have this 12v signal, trigger arduino to do something like turn a servo or power an led?
