Hello,

i have teard apart a magnetic card reader and extended some wires so i can add the reader to my arduino.
I got 4 cables: 5v, ground, data+ and data-

i have been searching around for hours to get help, but have not found any. I am pretty new to arduino, only made a couble of simple projects... but, how do i read the data which my cardreader sents?

If you have connected a wire that outputs negative voltages to the Arduino, I'd recommend that you NOT do that to your next Arduino.
