LED strip driver

Introduction

The LED Strip Driver with a 4-pin interface provides easy connectivity to your standard Arduino device.

It can help you control the luminance of a single-color LED strip, as well as the color and the luminance of an RGB LED strip through Arduino.

It has 2 terminals and 2 interfaces. The power for LED strip comes in through the 2-pin terminal. And the LED controlling voltages output through the 4-pin terminal. The 2 interfaces are screen-printed “IN” for controlling data input and “OUT” for controlling data shared with the next strip driver, respectively.

It can drive an LED strip 1 to 2 meters long with 9 V, while 1 to 5 meters long with 12 V. The driver in conjunction with the colorful LED strips can add a wonderful effect to indoor or outdoor usages

Features

• compatible interface (3.3V/5V)

• Can be cascaded for a larger display, with each unit having independent outputs

• Best results achieved with LED strips 5 meters long or shorter

• Outputs PWM signals

• 256 gray-levels are adjustable via programming

• Arduino and MEGA compatible

• Screw Terminals (power input and control signal output interface)

Application Ideas

• Delightful stage light effect

• Indoor light decoration

Specification

Interface Description

• 12V power supply – Screw terminal for 9-12v power supply.

• Chainable Input – Connected to Arduino or the other driver's chainable output. Pin definition: CLK DIN NC GND.

• Chainable output – Connected to the other driver's chainable input. Pin definition: CLK DOUT NC GND

• LED strip interface – Screw terminals for LED strip. Pin definition: + B R G

Note: VCC of Arduino is not connected to the interface.

Usage

Programming

• Step 1: Download the LED Strip Driver library here and import it into Arduino-1.0 Libraries: ..\arduino-1.0\libraries.

• Step 2: Run Arduino and open File\Examples\LEDStripDriver\. There are 3 options DemoForWhiteLEDStrip, DualLEDStrip, and SingleLEDStrip.

• Step 3: Select the right Arduino board you are using, like Arduino UNO or Duemilanove or others, and select the right downloading serial port.

• Step 4: Upload the DualLEDStrip demo. Then you can see the alternate colors of red,green,and blue of the LED strip.
