The product number of mCookie Sensor—Color LED Strip: MSDL12

mCookie Sensor-Color LED Strip is a lamp strip composed of 7 WS2812 lamp beads cascaded. Cascading multiple LED strips through IN/OUT interface can singly control each lamp bead.

Introduction of Sensor Pin

Pins of the sensor: PIN1: GND PIN2: VCC General signal pins: PIN3(IO1): digital/analog signal PIN4(IO2): NC(null) Special signal pins: If it is IIC: IO1/IO2 are respectively SDA/SCL. If it is soft serial port: IO1/IO2 are respectively tx/rx.

Special to Sensor-Color LED Strip sensor pins PIN1: GND PIN2: VCC PIN3(IO1): Digital signal output PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.

Features

• Single bus control, only one I/O to control, and complete the receiving and decoding of the data;
• With built-in IC control, serially connecting the cascade interfaces can realize cascaded control ;
• The color of the three primary colors of each pixel can achieve 256-level brightness display, and complete 16777216-color whole true color display, and the scanning frequency is not lower than 400Hz/s.

Specification

• Voltage of the sensor
  • 3.3V~5V working voltage

• Size of the sensor
  • Size of the board
  • 1.27mm-spacing 4Pin interface connected with sensorhub
  • CAD drawing of the sensor: File:Sensor CAD.zip

• Function description
  • Adopts WS2812 integrated control light source;
  • RGB of each pixel can realize 256-level brightness display;
  • When the update rate is 30frame/s, the cascaded number is not less than 1024;
  • No circuit is needed to be added when the transmission distance between any two points is not over 3 meters.

• Connection
  • This sensor can be connected to the following interfaces of the core: D2~D13
  • Multiple sensors cascaded: Connect the (OUT) of the former LED—Strip to the (IN) of the later LED-Strip.

Development

Program Download

• Download and unzip the program File:Microduino Color LED Strip Test.zip

And you can also use the program Senso_LED_WS2812 in the third party sample of Arduino IDE , which has richer colors.

Program Download

• Follow the Software Getting Started Guide.
• Select the Board, Processor and Port.
• Click [File]->[Open], browse to the project program address, and click "Microduino_Color LED Strip_Test.ino" to open the program.
• After confirming all these items are correct, click "→" to download the program to the development board.

Hardware Setup

• Referring to the following picture, connect Sensor-Hall to the digital port of Microduino-Sensorhub.

Result

• After download, observe the LED strip.
• LED twinkles in red, green and yellow successively with 1s as the interval.

Application

• LED full-color luminous character lamp strip, LED full-color module set, LED full-color soft lamp strip and hard lamp strip, and LED guardrail tube.

Projects

• Bluetooth Lamp
• Rhythm Lamp
• Applause Enthusiasm Detection
• Colored LED
