Raspberry Pi - LED and Button Projects

ARecord press time and only toggle if press duration > 0.5 seconds

BAdd a fixed delay of 0.5 seconds after every toggle regardless of press

CUse GPIO.setup with pull_down resistor instead of pull_up

DToggle LED twice quickly to confirm press

Step-by-Step Solution

Solution:

Step 1: Understand debounce by filtering short presses
Measure how long button is pressed to ignore quick accidental presses.
Step 2: Implement timing logic
Record time when button is pressed and released; toggle LED only if duration exceeds 0.5 seconds.
Final Answer:
Record press time and only toggle if press duration > 0.5 seconds -> Option A
Quick Check:
Debounce by timing press duration = A [OK]

Quick Trick: Use timing to filter out short button presses [OK]
