hello everyone,
i need to design an automatic attendance system for my digital logic design project.. i am stuck at the counter. have 8 students whose attendence is to be counted for the whole week. whenever a student enters his roll# circuit has to add 1 to the previous number which corresponds to the number of time that roll# has been entered previously..
can any one help me with this??
Need a little more info: just one counter? how high do you want it to count? how will you display or otherwise access the count? advance count by pushbutton?

how can i use 74LS90 for as counter going from 0>1>2>3>4>5>6>7>0... using push button for advanced counters.. is there any other IC which can be used for the same purpose??

no, its basically a semester project of digital logic design.. i am designing an attendence system for a class of 8 students.. the student enters his rol# which is converted into binary (3 bit) which is then put into a decoder to get 8 outputs.. after this, to count for the time any rol# is entered and display the count on 7 segment i need to design a counter...
