Hardware

We connect according to the following:

  • D2 of Arduino to CLK of Linker 4-digit 7-segment module
  • D3 of Arduino to DIO of Linker 4-digit 7-segment module
  • +3.3V of Arduino to VCC of Linker 4-digit 7-segment module
  • GND of Arduino to GND of Linker 4-digit 7-segment module


Software

The source files for linker kit is hosted at [ https://github.com/linksprite/Linkerkit/tree/master/Linker_4D7SLED github[. Please download and put under the library path of Arduino IDE, and rename the directory name as DigitalTube as shown below:
