Description

Usually 4 digit display module is a 12 pin module. But in our Crowtail gadget, we utilize a TM1637 to scale down the controlling pins into 2 Crowtail pins. It only takes 2 digital pins of Arduino or Crowduino to control the content, even the luminance of this display. For projects that require of alpha-numeric display, this can be a nice choice.

Model: CT0060FDD

Features

  • Compatible with Crowtail interface
  • 4 digit red alpha-numeric display
  • 8 adjustable luminance levels
  • Dimensions(mm):40.0(L)x20.0(W)x12.8(H)

Application Ideas

  • Time display
  • Stopwatch
  • Sensors' input display

Usage

The following sketch demonstrates a simple application of digital display.

1.Hardware Connection.

2.Download the library Crowtail- 4-Digit Display library; Unzip and put it in the libraries file : ..\arduino-1.0\libraries;

3.Open “_4Digital7_SegmentLED ” example via the path: File --> TM1650 --> Examples --> _4Digital7_SegmentLED.

int8_t number[] = {0,0,0,0};
void setup()
{
	//Serial.begin(9600);
}

void loop()
{
    DigitalLED.clearDisplay();
     delay(1000);
     DigitalLED.display(0,TubeTab[1]);
     DigitalLED.display(1,TubeTab[2]);
     DigitalLED.display(2,TubeTab[3]);
     DigitalLED.display(3,TubeTab[4]);
     delay(1000);
     DigitalLED.clearDisplay();
     delay(100);
     DigitalLED.display(0,TubeTabwithPoit[5]);
     DigitalLED.display(1,TubeTabwithPoit[6]);
     DigitalLED.display(2,TubeTabwithPoit[7]);
     DigitalLED.display(3,TubeTabwithPoit[8]);
     delay(1000);
}

4.Upload it into your Crowduino board and observe the Digit-Display.
