Green LED 3mm Diffused — General Purpose, 10-Pack for Arduino, Breadboard & Compact PCB Projects
The 3mm diffused green LED is the compact general-purpose go/ok/power indicator LED for Arduino, breadboard, and space-constrained PCB projects. At 3mm diameter, this LED fits into tight PCB layouts and compact enclosures where standard 5mm LEDs are too large. Green is the universal go/ok/power-on color in electronics — instantly communicating a normal, ready, or active state to the user.
The diffused lens scatters light evenly across a wide viewing angle. Green LEDs have a forward voltage of approximately 2.0–2.4V, making them compatible with both 3.3V and 5V Arduino circuits with a current-limiting resistor. Supplied in a 10-pack.
Key Features
- 3mm through-hole package — compact size for space-constrained PCB layouts
- Diffused lens — wide viewing angle (~120°)
- Green color — universal go/ok/power-on/ready indicator color
- Forward voltage ~2.0–2.4V — compatible with 3.3V and 5V circuits
- 10-pack
How to Use with Arduino
- Connect the anode (longer leg) to an Arduino digital output pin through a 220–330Ω current-limiting resistor
- Connect the cathode (shorter leg) to GND
- Set the digital pin HIGH to turn on, LOW to turn off
Typical Applications
- Power-on and ready indicators — green is the universal go/ok/power-on color
- Traffic light Arduino projects — go signal in traffic light projects
- Compact PCB status indicators — ok and ready indicators on miniature PCBs
- Wearable electronics — small LED indicators for wearable devices
- Robotics and automation — ready and ok status indicator LEDs
- Educational electronics kits — STEM and electronics learning projects
