LEDs require a 220Ω resistor in series to prevent burnout. Ensure correct polarity: longer leg is anode. Use red wire for 5V, black for GND.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
