TRAFFIC LIGHT MODULE

Description

A traffic light module is a device that replicates the functionality of a traffic light system. It typically consists of multiple LEDs arranged in a standard traffic light pattern, including red, yellow, and green lights. The module is designed to be used in various applications, such as traffic light system models, DIY projects, and educational purposes.

Key Features and Specifications:

• The traffic light module is compact in size and easy to install.
• It usually includes large LEDs, typically 8mm in size, for better visibility.
• The LEDs are often active HIGH, meaning they are lit when a logic HIGH signal is applied to the module’s pins.
• Built-in current limiting resistors ensure that the LEDs receive the appropriate amount of current.
• The module is compatible with both 3.3V and 5V systems, making it versatile for different microcontroller platforms.
• Some modules can be connected to the PWM (Pulse Width Modulation) pin of a microcontroller to control the brightness of the LEDs.
• The module can be directly connected to the pins of an MCU or plugged into the female header of Arduino boards.

Applications:

• Traffic light system models: The traffic light module is commonly used in miniature traffic light displays for educational purposes or model train layouts.
• DIY projects: It can be integrated into various DIY projects, such as home automation systems, interactive displays, or signaling systems.
• Educational purposes: The module is often used in electronics and programming courses to teach concepts related to microcontrollers, digital signals, and control systems.
