Verify that the speaker makes a clear, audible tone while the Debug Terminal
displays “Testing piezospeaker…”.
Use the Debug Terminal to verify that the BASIC Stamp still receives a zero
from each IR detector when an object is placed in front of it.
Verify that the LED next to each detector emits light when the detector detects
an object. If one or both of the LEDs appear not to work, check your wiring and
your program.
