The data is shown as number, not "General, I set that up previously. When I set the Arduino Sketch to send "12.56" to the eXcel, it displayed "12.56" in the cell. So the problem is not with eXcel. When I set "volts" to use the input from A(0), I do not get floating point.
#define sensor A0
void setup() {
Serial.begin(9600);
Serial.println("CLEARDATA"); //clears any data from previous projects
Serial.println("LABEL,Time,Timer,volts"); //always write LABEL, so excel knows the next things will be names of columns (the example on line used Acolumn, Bcolumn)
Serial.println("RESETTIMER"); //resets timer to 0
// put your setup code here, to run once:
}
void loop() {
float volts=sensor
;
volts=analogRead(sensor);
Serial.print("DATA,TIME,TIMER,");
Serial.println(volts,4);// put your main code here, to run repeatedly
delay(2000);
}
