I have a few questions about 7-segment LED displays.
When we build a circuit using 7 segment (common-anode) and decoder (7447), we also use 4 tactile switches to make combinations. Should I directly connect switches to Vcc or ground (I have no knowledge about that) or what should I do with switches, after completing rest of circuit i.e. resistors to IC, IC to Vcc and display to Vcc?
I still need the answer but I think I did it!
