How to two digits 7-segment counter?
How to two digits 7-segment counter?
(OP)
hi all
i have recently tried to build a 1 digit 7-segment display using 4511 to display number from 0 to 9, using a BCD rotary switch as input to the chip.
How can I build a 2-digit 7-segment allowing me to display counter value from 0 to 15, using a 4-bit rotary swtich?
I do not know what chip to use to convert a 4-bit binary number to two 4-bit BCDs to drive two 4511 each connected to a 7-segment. Are they other ways to do this?
Please help...

microcontroller. All of the development software is free, but you would need to build a programmer (schematics are on-line) or buy one. If you're going to do hobbiest projects in the future it's a good low cost investment.
