## Description

Ideal for simulating a traffic light in Arduino projects and other development boards, the module includes red, yellow and green LEDs with integrated resistors for direct connection to 3.3-5V. It quickly mounts on a breadboard, has digital inputs and a common cathode interface, and offers a compact 56mm form factor for easy prototyping and testing.
Traffic light LED module with three LED diodes, Red, Yellow and Green, compatible with Arduino and other development boards.
This module can be placed directly in the Breadboard and does not require the addition of resistors, as they are already integrated in the module, which is why it can be connected directly to the development boards on both 3.3V and 5V.
