Description
LED 3mm Diffused Red – Through-Hole Indicator LED
The LED 3mm Diffused Red is a compact and energy-efficient through-hole LED widely used for status indicators, signal circuits, DIY electronics, and embedded systems. Its diffused lens produces a soft, wide-spread red glow, making it excellent for applications where uniform visibility is required rather than sharp, focused lighting.

How to Use
- Connect the longer leg (anode) to the positive voltage via a resistor.
- Connect the shorter leg (cathode) to ground.
- Recommended resistor: 330E to 1K based on supply voltage.
- Control the LED using GPIO pins of microcontrollers like Arduino or PIC.
- Use PWM for brightness adjustment if needed.
