Which value range is valid for setting the brightness of a
PWMLED object in gpiozero?Which value range is valid for setting the brightness of a PWMLED object in gpiozero?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Recall PWMLED brightness range
Brightness is set using a float between 0 (off) and 1 (full brightness).Step 2: Check options for correct range
Only 0 to 1 as float matches the expected input; others are incorrect ranges or types.Final Answer:
0 to 1 (float values) -> Option DQuick Check:
Brightness range = 0 to 1 float [OK]
Quick Trick: Brightness uses float 0.0 to 1.0 range [OK]
Common Mistakes:
- Using integer 0-255 instead of float
- Using percentage values directly
- Using negative values
