Compatibility
These standard through-hole LEDs work with any 3.3V or 5V microcontroller platform—Arduino Uno, Nano, ESP32, Raspberry Pi Pico, or 555 timer circuits. Always add a current-limiting resistor (typically 100–330 Ω) between the anode and the I/O pin to prevent damage.
Wiring Notes
Solder 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.
Why Buy from Compoden
Every 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.
Is this compatible with Arduino?
Yes, 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.
What resistors should I use?
For 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.
Are the LEDs pre-sorted by colour?
The pack includes a mix of all five colours and both sizes, but they are not individually bagged or labeled. You can visually identify each colour by looking at the clear lens under light.
