Microduino-ColorDetector

The product number of Sensor-Color Detector is: MSDT51

Microduino-Color detector is a color detection sensor.

This module adopts TCS3414CS color chip. Based on 8×2 filtered photodiode and 16-bit analog-digital converter, you can measure light or light reflection on the surface of an object to acquire color value.

Introduction of Sensor Pins

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 Detector sensor pins PIN1: GND PIN2: VCC PIN3(IO1): SDA(IIC communication) PIN4(IO2): SCL(IIC communication) Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.

Development

Preparation

• Make sure you build Microduino IDE or refer to: Microduino Getting started
• Core selection
  • 1. Adopt Microduino-CoreUSB or mCookie-CoreUSB as the core.
  • 2. Adopt Microduino-Core or Microduino-Core+ as the core plus Microduino-USBTTL as the program download module.

Program

[MicroduinoColorSensor]

• Define variable values; RGB reading range.

  #define redMax 32767
  #define greenMax 32767
  #define blueMax 32767
  int redValue,greenValue,blueValue;

• readRGB(); Read RGB color function

• Reflect RGB value (0~32767) to (0.225);

 redValue=map(red, 0, redMax, 0, 255);
 greenValue=map(green, 0, greenMax, 0, 255);
 blueValue=map(blue, 0, blueMax, 0, 255);

Hardware Buildup

• Connect the sensor to the IIC interface of the Sensorhub with a wire.

Microduino-Sensorhub

mCookie-Hub

• Connect the core, Sensorhub and the Color Detector to a computer with a USB cable.
• Select the right board and COM port, compile and download. You can refer to AVR Core：Getting started

• Download the program above.
• Select the right port from Tools→Serial Port in Arduino IDE and then download program.
• Open the serial monitor after download. The console will print current RGB value circularly.

Application

Microduino-Color detector is suitable for environment color detection.
