Step-by-Step Solution
Solution:
Step 1: Understand duty cycle to angle mapping
At 50 Hz, about 2.5% duty cycle corresponds to 0°, 7.5% to 90°, and 12.5% to 180°.Step 2: Match 12.5% duty cycle to angle
12.5% duty cycle sets the servo to its maximum angle, 180°.Final Answer:
180 degrees -> Option DQuick Check:
12.5% duty cycle = 180° [OK]
Quick Trick: Max duty cycle ~12.5% means 180° angle [OK]
Common Mistakes:
- Confusing duty cycle values with angles
- Assuming 12.5% is 90 degrees
- Thinking servo can rotate beyond 180 degrees
