Project #3: Binary Numbers Display

More questions and more answers.

1. By manipulating switches, any binary number from 0-15 can be shown on the LED readouts.
2. What switches must be turned on to make the numbers 2         2       , 3      1 and 2     , 5      1 and 3     , 13      1, 3, and 4     ?
3. What is the maximum count that can be achieved with 3 LEDs?    7   . With 5 LEDs?    31  .
4. What is the relationship between the maximum count that can be achieved with a number of LEDs and the weight of the next LED if it were added?

value of next LED - 1 = maximum value of LED


Have a nice day!

Oh, and any questions?
