Reading for Nov. 22:

Horowitz & Hill,     Sec. 8.24-8.35     (review)
Hayes and Horowitz,    pp. 375 - 393

Exercises 8.28 (p. 527);  A.E. 13, (p. 559)

Lab Exercises:
 
   14.4    Counters from FF's

   14.5 a,b    Switch bounce

   14.6    Shift register         (74HC175)

Note: Plan to keep circuits from 14.6 on for several lab periods, as you will reusing at least parts of the circuits (starting with Exercise 14.6, which is used in 15.7). You can use a separate breadboard - no power supply - if you find that convenient.  These more complicated circuits will require more attention to neat layout:  Wires cut to proper length, close to the board, color-coding, etc.

Caution! Be very careful inserting and particularly removing this chip, as the pins bend easily. After a few bends they will break off and we will not have enough counters for the following labs.

  15.4      Displays    (Take care to keep pins straight on these too! They are relatively expensive.)

      15.5      "Keypad to counter"    [Omit A ...capacitance meter]
                                                      (Check Hayes and Horowitz, p. 371-4)
      15.6      Stopwatch

      15.7      Period meter (uses circuit from 14.6).
