Make software that will show the time with binary numbers with the same LED layout as shown in the image. There are two serial to parallel chips (74HC595) driving the first 5 columns of LEDs, the last column (right most column) is connected directly to uC's PB1-PB4 ports.
The time will set by two (hours minutes) 3-bit grey code rotery encoders attached to pins on the uC of your choice.
This project should take an hour for most half an hour if you're skilled.
