Figure 4.4 Photon wired to an LED.


             For this experiment we are going to use the same program we used earlier when we
        tested  the  voltage  outputs  using  the  DigitalWrite  function  to  set  the  output  to  either
        HIGH or LOW.


        int digitalpin = D0;



        void setup() {


          pinMode(digitalpin, OUTPUT);



        }


        void loop() {



          digitalWrite(digitalpin, HIGH);


          delay(1000);



          digitalWrite(digitalpin, LOW);


          delay(1000);


        }
