ACTIVITY #3: UNCOMMITED INPUTS AND CONDITIONING SWITCHES
An uncommitted input is one not dedicated to a voltage potential, is said to be “floating”
and may not be sensed by the BASIC Stamp as a definite logic HIGH or LOW. Simply
connecting a mechanical switch between the input and Vdd leaves the input floating
when the switch is open. Current flow to Vdd or Vss is necessary to “commit” the input
(when in the open condition). This exercise will help make this concept clear.
