Wiring with Arduino Uno
Connect using a current-limited resistor, as follows:
CopyEditArduino Pin (e.g. D13) → 330 Ω resistor → LED Anode (+ long leg) LED Cathode (– short leg) → Arduino GND
Using a 5 V output, a 330 Ω resistor limits current to ~10 mA:
(5 V – 2 V) ÷ 330 Ω ≈ 9 mA
Applications
Power and status indicators
Visual notifications in robotics and IoT
Panel lights and signage
Educational electronics and breadboard projects
Nightlights and low‑power illumination
