FAQs:
Q1: Do I need a resistor with this LED?
A: ✅ Yes. Use a 220Ω–330Ω resistor when powering from 5V to limit current.

Q2: Can I use it directly with Arduino pins?
A: Yes, just connect it with a current-limiting resistor in series.

Q3: What is the polarity?
A: The long leg is positive (anode), and the short leg is negative (cathode).

Q4: Is it suitable for 12V circuits?
A: Use a proper resistor (around 470Ω–1kΩ) for 12V operation.
