3 mm Yellow LED (Pack of 10) A Yellow light-emitting diode (LED) is a semiconductor light source. LED's are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white led and illuminate's blue light. When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the colour of the light (corresponding to the energy of the photon) is determined by the energy bandgap of the semiconductor. read our blog about Turning on an LED with your Raspberry Pi’s GPIO Pins which explains controlling led with raspberry pi .

What is the forward voltage and current of the 3 mm yellow LED?
Typical forward voltage is 2.0–2.2V with a recommended forward current of 20mA. Use a current-limiting resistor for safe operation.
Can these LEDs be used with Arduino or Raspberry Pi?
Yes, they are fully compatible with Arduino, Raspberry Pi, ESP32, and other 3.3V/5V microcontrollers.
Do I need a resistor when connecting the LED?
Yes, always use a current-limiting resistor (e.g., 220Ω for 5V supply) to prevent damage to the LED.
What is the viewing angle of these LEDs?
Standard viewing angle is approximately 30–45 degrees, suitable for indicator and display applications.
