I am almost completly new to arduino. All i've ever done with it was making led's blink. So, I'm kinda desperate right now, i have around 19 hours to finish this project i just got assinged with.
Basically i have to read from an Sonmicro 2300 RFID reader (yes this exists, it's written on the reader itself but i cant find it by googling) the UID from a tag with my Arduino micro. The reader is correctly wired to the RX-Pin (which should be pin 4, but im not sure). The whole question is basically, how can i read from the RX-pin, which i believe is pin4. I dont have more information myself so i would be glad for any hint. A simple example of reading something from this pin would be great, i wont understand the complicated ones anyway...
Hopefull regards Nodua
