hard📝 Application Q9 of 15

Raspberry Pi - gpiozero Library

AUse button.when_pressed with button.hold_time = 0.5

BSet button.hold_time = 0.5 and use button.when_held callback

CAdd time.sleep(0.5) inside callback

DUse button.when_pressed with a delay loop

Step-by-Step Solution

Solution:

Step 1: Understand debounce with hold_time
Setting hold_time defines how long button must be held to trigger when_held.
Step 2: Use when_held callback for presses longer than 0.5s
Assign callback to when_held and set hold_time = 0.5 to ignore shorter presses.
Final Answer:
Set button.hold_time = 0.5 and use button.when_held callback -> Option B
