Have this assignment for an online digital electronics class. Instructor says information in my text is not sufficient to complete the project. Good textbook selection. Does anyone have any idea how I can start this. Tried using Full adders but I cannot figure out how to convert output back to decimal 1-10. This circuit uses ten switches to represent the ten pins used in bowling, with the switches (pins) arranged as shown below. The user closes a switch to indicate a fallen pin. As more switches are closed, a two-digit 7-segment display shows the number of fallen pins, from 00 to 10. For example, if switches (pins) 1, 3, 5, and 8 are closed, the display should read 04. Any help would be appreciated. Consulted numerous sources, but I am so lost I could be looking right at the answer and would not know it.
