Check Your Understanding:
  1. 1. On the LCD’s Screen, how many characters can one row hold?
    2. 10
    12
    15
    16
  2. 2. True of False: It is important to have your LCD Display code within a While Loop if you want the information to be continually updated.
    3. True
    False
  3. 3. What are some helpful uses of the LCD display:
    4. Real-time display of sensor values
    Displaying the name of the current program as it runs.
    Using the buttons to run different parts of the code.
    All of the above
  4. 4. Why do you still need to provide a time duration when continuously updating the LCD with a while loop?
    5. The while loop repeats faster than the LCD can display information, causing the text to flash repeatedly. Due to this, time is added in the form of a wait command to slow the loop and allow the LCD to refresh.
    The LCD refreshes faster than the loop, causing extra characters to appear on the screen while running. Due to this, a wait command is added to slow down the LCD and allow time for the while loop to catch up.
    The while loop is lazy, and doesn’t feel like working if it has to go fast. To keep the while loop from going on strike, a wait command is added to make it happy.
    All of the above
