If you’re using the Arduino related platforms for the first time, the Arduino Applications tutorial will help you get started.

The code below shows the control of the LED sign using the interface board. To create your own animations, all you have to do now is adjust the loop area according to your own wishes.

#include <ESP8266WiFi.h>

class WEMOSLEDCtrl {
  const int ENABLEOUTPUT = D0;
  const int SHIFTREGCLR = D5;
  const int SERIN = D6;
  const int SHIFTREGCLK = D4;
  const int REGCLK = D3;
  const int BUTTON = D7;
  const int LDR = A0;

  unsigned int value;

    digitalWrite(ENABLEOUTPUT, HIGH); // active low!
    digitalWrite(SHIFTREGCLR, HIGH); // active low!
  }

  }

      // aktiviere Schiebeaktion
