Hi forumers,
I have some problems with this RFID reader (Wiegand RFID Reader: RFID-IDR-WIEGAND)
1) does any of you have the datasheet for this product? mind sharing?
2) how to control the buzzer and the LED. the buzzer is too loud, i hope can turn it off without breaking the reader's case. i tried to pull down the cable for buzzer (give LOW signal) but the sound still comes out.
Please help, thank you.
