The 3mm White LED (Light Emitting Diode) is a compact and energy-efficient electronic component commonly used in Arduino projects, robotics, DIY electronics, and indicator circuits. Its small 3 mm round package makes it perfect for breadboards, prototype boards, and PCB-based designs where space is limited.
This LED emits a bright white light and typically operates at a forward voltage of around 3.0 V to 3.4 V with a recommended current of about 20 mA. A current-limiting resistor should be used in series to ensure safe operation and prevent damage to the LED.
