    #define echoPin A4
    LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

    Upload the program
    

    Read distance on LCD Screen

     

    Activities:

    1) Set the HC-SR04 sensor 10 cm from a large flat surface. 

     

    Note the location of 0 cm on the sensor.

     

    (Front Edge?, at PC Board?, 1/2 way to PC Board?...)

     

     

    2) Measure 8 known distances and record sensor reading.

     

    Calculate % error = 100(a-e)/a where a = accepted, e = experimental

    

    3) What are the shortest and longest distances the Ultrasonic measures accurately?

    4) Are there surfaces that are "invisible" to the sensor?  (absorb the sound and give erroneous readings?)

    
    

    5) Extra Credit:

    Create a program to scroll an Appropriate message across the LCD display.
