I got a RFID module for my Arduino.
On the backside it says "RFID_Module_v1.1", but no label or anything saying who made it or whatever, so I'm asking for guidance here.
The project is about blind people. I want to place a RFID chip under a milk carton and then I hooked up a beeper to my Arduino. When the blind person moves the milk over the RFID reader it should beep as many days there's left untill it expire. For example, if it's good for 3 days, it should beep 3 times.
There's 4 outputs on the module. GND VCC RXD TXD
So far I've hooked GND to ground on my Arduino UNO, and the VCC to 5 volt. I got an idea that RXD and TXD is the reader and writer outputs, but where should I connect them?
Can anyone hook me up with some coding that will allow this module to beep when the card is over it? If you have questions regarding this, feel free to ask and I'll answer :)
Thanks in advance!
