// Data wire is plugged into pin 2 on the Arduino #define ONE_WIRE_BUS 12

const int analogVoltPin = A2; const int analogCurrentPin = A1; float amp=0;

OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature. DallasTemperature sensors(&oneWire);

Serial.println("CLEARDATA"); //clears up any data left from previous projects Serial.println("LABEL,Time,Detik ke-,Data"); //always write LABEL, so excel knows

the next things will be the names of the columns (instead of Acolumn you could write Time for instance)

Serial.print("DATA,TIME,TIMER,");//writes the time in the first column A and the time since the measurements started in column B
