See the Wiring section above and the User Guide linked below for recommended values. 💡 Tips The green channel is significantly brighter than red — reduce green/blue PWM values when mixing to achieve balanced white or pastel colors. Clear-lens LEDs produce a focused beam — ideal for indicator lights but can be intense to look at directly. Consider diffused LEDs for softer, more evenly distributed light. On 3.3V systems, the green and blue channels (Vf = 3.5V) may not light reliably. Use a 5V supply for full-color operation. Use a helper function to invert PWM values so you can write standard 0–255 logic: analogWrite(pin, 255 - value); ⚠️ Important Notes Always use current-limiting resistors — driving an LED without one will destroy it. Do not exceed 20mA forward current per color channel. Observe correct polarity — the common anode pin connects to positive voltage, not ground. These LEDs are not waterproof. 📄 Documentation & Resources For detailed wiring diagrams, resistor calculations, Arduino code examples, and color mixing tutorials, see our full User Guide: 5mm Common Anode RGB LED User Guide All LED, Laser & Light Source User Guides Sold and supported by Envistia Mall.
