Hey guys I hooked magnetic read head to arduino board to see if arduino can read what cards I swipe. I also have lm386 in the max to amp the magnetic head.

My question is, since its all binary, what pattern should I look for to find the data from the card that was swiped?

I read some places that there will be leading 0 (aprox 20 or 60) and at the end, and I did come across similar pattern (40-80 leading/trailing 0) and I went to convert it to decimal and ascii (in case the track had holder info.

Also whats the purpose of the head common pin on the magnetic read head?
