And then send the last data w/ println(). On the Processing side, inside serialEvent(), use Serial::readString() + PApplet.splitTokens() in order to get all the data as a String[] array. Of course, you’re still gonna need to conver…

> The solution I gave on that link expects the Arduino C code to send the multi-data as if they were a row of tab-separated values (TSV): face_with_monocle That is, each value is followed by a \t character; except last 1, which is followed by an \n instead: nerd_face Serial.print(temperature); Serial.write('\t'); Serial.print(masse); Serial.write('\t'); Serial.print(humidite); Serial.write('\t'); Serial.print(comptage); Serial.write('\t'); Serial.println(son); // implies '\n' At the Pro…
