Always add a current-limiting resistor (typically 100–330 Ω) between the anode and the I\/O pin to prevent damage.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eSolder the longer lead (anode) to the GPIO via a resistor and the shorter lead (cathode) to ground. For 5V systems, use a 220 Ω resistor for red, yellow, and green, and 100 Ω for blue and white; for 3.3V, reduce to 100 Ω and 50 Ω respectively to maintain safe brightness.\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. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, each LED functions with any Arduino digital pin when using a 220-ohm resistor for red, yellow, or green, and a 100-ohm resistor for blue or white on a 5V board.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat resistors should I use?\u003c\/summary\u003e\u003cp\u003eFor 5V circuits, use 220 Ω for red\/yellow\/green and 100 Ω for blue\/white. For 3.3V, use 100 Ω and 50 Ω respectively. This keeps current near 20 mA for safe, bright output.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eAre the LEDs pre-sorted by colour?\u003c\/summary\u003e\u003cp\u003eThe pack includes a mix of all five colours and both sizes, but they are not individually bagged or labeled.
