Here is a simple example of sending data from Arduino to PureData over serial

Using Arduino Interfacing w/ Software on the Computer

Hi everyone, some time ago i made a simple exercise in sending data from an Arduino to PureData over serial, and i would like to share a video of it. The Arduino code is simply a 16-step step sequencer, like so:

int i = 0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  step = i % 16;
  Serial.write(step);
  i++;
  delay(200);
}

And you can see my PureData patch in the video. It uses the comport object to communicate with the Arduino, and the hslider object is limited to values between 0 and 15. You can find the video here on YouTube
