Description
These 3mm Bi Colour LEDs combine red and green light outputs in a single compact, through-hole package with a soft diffused lens for wide-angle visibility.
Featuring a 3 pin common anode configuration, they are ideal for visual indicators, control panels, Arduino and Raspberry Pi projects, and educational electronics.
By controlling each cathode pin independently, you can display red, green, or a mix (yellowish) using PWM or toggled input.
