After adding the LedSpeaker PIN directive to this program, you can make the LED
flash on/off while you hold down the pushbutton. All it takes in an
IF...THEN added to
the
DO...LOOP in the main routine.
√ Save a copy of the program as TestPushButtonYourTurn.bs2.
√ Add the
PIN directive LedSpeaker PIN 5.
√ Replace the
DO...LOOP in the Main Routine with this one:
DO ' DO...LOOP repeats indefinitely
DEBUG BIN1 pbSense ' Display state of pbSense (IN6)
IF pbSense = 1 THEN ' Flash LED if pbSense = 1
TOGGLE LedSpeaker
ELSE
LOW LedSpeaker ' Otherwise, keep pin low
ENDIF
PAUSE 100 ' Delay for slower PCs

√ Run the program and verify that you now have pushbutton control of the LED.
√ Save the modified program.
√ For fun, try modifying the program so that it plays a list of notes when you
press/release the button.
