Sample Code and Setup
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:
Launch the Arduino IDE and select the example code as below:
The running effect is shown below:
