The 5mm Orange LED (Light Emitting Diode) is a compact and energy-efficient component widely used in electronics projects, Arduino circuits, robotics systems, and indicator applications. With its standard 5 mm round through-hole package, the LED can be easily used on breadboards or soldered onto PCBs, making it suitable for both beginners and professional electronics developers.
This LED produces a bright orange light with a typical wavelength around 600–610 nm, making it ideal for status indicators, signal lights, and control panels. It generally operates at a forward voltage of about 1.8 V to 2.2 V with a recommended forward current of around 20 mA, so a current-limiting resistor should be used when connecting it to a power source or microcontroller.
The LED features a two-lead through-hole design, where the longer lead represents the anode (positive) and the shorter lead represents the cathode (negative). This simple configuration makes it easy to interface with development boards such as Arduino, ESP32, Raspberry Pi, and other microcontroller platforms.
