In this Grove gadget, we utilize a TM1637 to scale down the controlling pins into 2 Grove pins. It only takes 2 digital pins of Arduino or Seeeduino to control the content, even the luminance of this display. For projects that require of alpha-numeric display, this can be a nice choice. Features 4 digit red alpha-numeric display Grove compatible 8 adjustable luminance levels Application Ideas Time display Stopwatch Sensors’ input display For all Grove users (especially beginners), we provide you guidance PDF documents.

Introduction Grove - 4-Digit Display module is a 12-pin module. In this module, we utilize a TM1637 to scale down the number of controlling pins to 2. That is to say, it controls both the content and the luminance via only 2 digital pins of Arduino or Seeeduino. For projects that require alpha-numeric display, this can be a nice choice.

Grove interface - Can be connected to digital port on Grove - Base Shield. 4 - digit display - Common anode digital tube. Pin definition: CLK DIO VCC GND Usage The module uses an LED drive chip - TM1637 to control the contents and change the luminance. Here we drive it to display time.

1. Connect the Grove socket marked "IN" on the LED Strip Driver and digital port 2 of the with a Grove cable. You can change to the digital port as you like. But don't forget to change the port number in the definition of the demo code at the same time.

2. Plug onto Arduino/Seeeduino or plug onto Arduino Mega.

3. Connect Arduino/Seeeduino to PC via a USB cable.

4. Download and . Unzip and put them in the libraries file of Arduino IDE by the path: ..arduino-1.0libraries. 5. Restart the Arduino IDE, open one demo code you like, for example ClockDisplay directly by the path:File -> Example ->DigitalTube->ClockDisplay.

6. Upload the demo code and the clock will be ticking in a few seconds. Please click if you do not know how to upload. You can see this:
