7-Color Flashing LED Module (KY-034 Class)

Description

TeknoCrafters FA3039 7-Color Flashing LED Module (KY-034 Class)

The TeknoCrafters FA3039 is a compact and vibrant 7-color flashing LED module, modeled after the KY-034 platform. It features a 5mm round RGB LED that automatically cycles through seven colors when powered, eliminating the need for external control or programming. This module is ideal for decorative lighting projects, visual displays, and educational demonstrations. It is compatible with microcontrollers such as Arduino, ESP32, and ESP8266. For Raspberry Pi users, an external analog-to-digital converter (ADC) is necessary due to the lack of native analog input.

Tri-Tek Electronics, located in Mesa, Arizona, is an authorized distributor of TeknoCrafters products. We ensure full manufacturer warranty coverage, competitive pricing, and direct factory support. Our retail location serves customers in Phoenix, Chandler, Tempe, Gilbert, Scottsdale, Glendale, and surrounding areas.


Features

  • LED Type: 5mm round RGB LED with built-in IC

  • Operating Voltage: 3.3V to 5V

  • Current Consumption: Approximately 20mA (varies with color)

  • Color Cycle: Automatic sequence of 7 colors

  • Dimensions: Approximately 18mm x 15mm x 10mm

  • Pin Configuration:

    • S (Signal): Connects to a digital output pin on the microcontroller

    • VCC: Power supply (3.3V to 5V)

    • GND: Ground


Example Applications

  • Decorative Lighting: Add dynamic lighting effects to DIY projects, art installations, or holiday decorations.

  • Visual Indicators: Use as status indicators in electronic devices or systems.

  • Educational Demonstrations: Demonstrate principles of color mixing and LED functionality in classroom settings.

  • Interactive Displays: Integrate into interactive exhibits or displays requiring visual feedback.

  • Prototyping: Incorporate into prototypes requiring simple, colorful visual indicators.


Installation Example

In a typical Arduino setup, connect the FA3039 module as follows:

  • Signal (S): Connect to digital output pin (e.g., D13)

  • VCC: Connect to +5V power supply

  • GND: Connect to ground

This configuration allows the LED to automatically cycle through its color sequence when powered, providing an easy way to add colorful lighting effects to your projects.
