SECTION 13Running a Seven-Segment Display

THE SEVEN-SEGMENT DISPLAY depends on two major chips. I introduce the “slave” 4511 first so you can understand how it is controlled. Then the 4516 “master” is introduced. You will investigate and play with most of the possibilities of each chip as they are presented. At the end of this chapter, you will have the prototype of the DigiDice and be able to explain it. Better than that, you will be able to control it. Remember, binary’s the word.

Here you have a real number output. It’s just a set of LEDs set up to represent numbers.

Here is the system diagram from the beginning of Part Three (see Table L43-1).

Remember that there is to be a number output too. ...
