although I think you upload an image
should I connect the head common pin to ground???
if I'm not wrong it's a comparator isn't it with a pull-up resistor at the output,
, but do you have what kind of signal should I be expecting to get in the arduino??
Ok, first thing tomorrow I'll got for the comparators and try to get the data from the card by this way, I was trying to use an interrupt to "catch" the signal peaks and store 'em in an array to generate the F2F signal.Nothing prevents you from using interrupts once the signals (clock and data) has been conditioned and turned into a digital signals. In fact a cardreader project posted here several years ago did just that, the clock pulse wired to a arduino interrupt pin and the data wired to any digital input pin.LeftyI'll try with the comparators,Thanks a lot for all the help
Hi I'm at this moment building the circuit with the comparators, I'm planning in using the interrupt to check when the card is being swiped, as far as the clock signal that lefty mentions I should feed the arduino with, where this signal come from?? the circuit with the comparators uses no clock right?? it just generates the F2F wave from the read head, am I wrong??Cheers,
