Hi there,
I bought this RFID reader: https://www.amazon.com/Wireless-134-2KHz-Contactless-Controller-Antenna/dp/B07WGX9WRW/ref=sr_1_1?dchild=1&keywords=134%2C2khz+rfid+module&qid=1602089872&sr=8-1
Pin definition:
1.GND
2.VCC
3.NC:No function, no use
4.TXD:Send data
5.NC:No function, no use
6.NC:No function, no use
7.L1:Connect to antenna
8.L2:Connect to antenna
The amazon page says that the reader has a TXD pin but I don't understand how I can connect this to my Arduino and what code I need to use to read the RFID chip implanted in my cat.
Is there anyone who can help me with this?
