' -----[ Program Description ]---------------------------------------------
'
' This program demonstrates the ability to use the 74HC595 and 74HC165
' together with the fewest number of BASIC Stamp IO pins.
' accomplished by placing a 4.7K resistor between the data out (pin 7) of
' the 74HC165 and the data in (pin 14) of the 74HC595.
' pin from the BASIC Stamp connects to the 74HC595.
