Please help .

gus2 mo k2lad ng project q dti...conversion of binary input to hex output ng 0000 to 1111...ung output nun 0-F...consists of 7411(3-input and gate) 7421(4-input and) 7404(inverter) 7432(or gate) 7408(2 input and) IC...ska isang 7 segment display...

i olready had d K-mapped equations ikkbit mo nlng s bredboard...

tanong lng..
diretso wiring nlng ba ito at lagay ng input at depende sa logic gate ang output?
o may mga programming pang kailangan?

di ko pa kasi na try eh.. 
sa scul kasi puro wiring lng kami ng logic circuits. then manual na pag trigger ng mga switch para maging [I/O] ang inputs..
