The Traffic Light LED Module has large Red, Yellow and Green LEDs arranged in a standard traffic light pattern with built-in current limiting resistors.
- Traffic Light LED Module
KEY FEATURES OF TRAFFIC LIGHT LED MODULE:
- Large 8mm Red, Yellow and Green LEDs
- LEDs active HIGH
- Built-in current limiting resistors
- 3.3 and 5V compatible
This module includes large 8mm Red, Yellow and Green LEDs arranged like a typical traffic light that are useful for experimenting with traffic signals, using them on a railroad model or as some type of good/caution/bad status indicators for a project.
The modules have current limiting resistors built-in, so they can be connected directly to the pins of an MCU. You can even plug it directly into the female header of most Arduino boards where you have 3 digital pins next to a ground, such as using the Uno pins 11, 12, 13 & Gnd. The LEDs are lit when a logic HIGH is applied to the pins.
- G = Green LED, active HIGH
- Y = Yellow LED, active HIGH
- R = Red LED, active HIGH
- GND = Ground
