RFreader reads the input fron the ID-card and sends it to microcontroller. mcu compares the same no with the available no's. If no. is matched then generates output pin high. Plz help in me in implementing the code in c.Total there are 250 different IDs available.
will you plz tell me how rfreader reads? whether it reads the no as string, as constant or, as char... when tested I am getting $9481300500 as output on the hyperterminal.
