need help for arduino scope

[lightbringer81]

i was trying to make an arduino oscilloscope for fun i did the one in this website

( http://www.homebrew-tech.com/arduino/brewing-arduino-announcement/usingarduinoasoscilloscope-arduinoscope)

but when i tried to compile it said BYTE is no longer supported use Serial.Write() and i knew i just cant cut and paste that to there

i also tried

http://www.instructables.com/id/Arduino-Oscilloscope-poor-mans-Oscilloscope/     but after i did all work when i tried to see waveform it just didnt do anything but a red line

can anyone help me for this please ? you can help me with code or 2nd with or it would be great if you link me a working one thanks all :=)

A bit more information would be good, we won't be able to help if you just say it doesn't work.
Give us some code, schematics, pictures, then maybe we can help

for first one: after i put all libraries and sketches to both arduino ide and processing i ran and upload the code on arduino but processing which should run the UI on my pc said BYTE no longer usable

second: in this one i upload all codes on both ide i ran them both when i touch the probe into a signal i wasnt able to see anything but a red line

i ll try replacing byte as show in that link thanks for help

and by the way i can run codes in processing showing error " The function readStringUntil(int) does not exist


// handle serial data
void serialEvent(Serial p) {
  String data = p.readStringUntil(LINE_FEED);
  if (data != null) {
    // println(data);
    vals = int(split(data, ' '));
  }
}
