In a common anode LED, all anodes share a positive voltage rail. These 5mm LEDs use the common cathode configuration, making them ideal for use with microcontrollers like Arduino that source voltage to individual pins.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use these 5mm RGB LEDs with an Arduino or Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! These LEDs operate at 2–3.4V with a 20mA working current, which is fully compatible with Arduino and Raspberry Pi GPIO outputs. Simply use a current-limiting resistor (typically 100–220Ω per channel) in series with each color pin to protect both the LED and your microcontroller.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these suitable for outdoor decorative lighting projects?\u003c\/h4\u003e\n\u003cp\u003eA: These LEDs are primarily designed for DIY, indoor signage, and ambient decoration.
