Another project in a similar vein is the Wekinator, which is featured in a free online course on machine learning for musicians and artists. Also building on the GRT is ml-lib, a machine learning toolkit for Max and Pure Data. Our project is part of a broader wave of projects aimed at helping electronics hobbyists make more sophisticated use of sensors in their interactive projects. Installations instructions are on our GitHub project page.

The software is still rough (and Mac only for now) but we’d welcome your feedback. We’re building on the Gesture Recognition Toolkit (GRT) and openFrameworks. The project is a part of my research at the University of California, Berkeley and is being done in collaboration with Ben Zhang, Audrey Leung, and my advisor Björn Hartmann.

#MAX MSP ARDUINO CODE#

We’re working on building up a library of code examples for different applications so that Arduino users can easily apply machine learning to a broad range of problems. The machine learning algorithms that power this pattern recognition are specified in Arduino-like code, while the recording and tuning of example sensor data is done in an interactive graphical interface. Our ESP (Example-based Sensor Predictions) software recognizes patterns in real-time sensor data, like gestures made with an accelerometer or sounds recorded by a microphone. for recognizing spam emails or recommending related products. Machine learning is a technique for teaching software to recognize patterns using data, e.g. This requires pd-extended to make use of the comport object.At Arduino Day, I talked about a project I and my collaborators have been working on to bring machine learning to the maker community. Ensure you have just one program using the Arduino at a time to prevent this.

#MAX MSP ARDUINO SERIAL#

Note: Having the serial object open in Max may prevent you from uploading to your Arduino from the IDE and vice versa. Now you can enjoy the freedom of using Max as another element in your modular set up! Have fun 🙂 With just a couple more objects we can build a random voltage generator:

#MAX MSP ARDUINO PATCH#

There you have it! Now you are free to create any patch you like, sending voltages up to 5V+ from your Arduino. In my case it’s port e. So change the serial object to serial e 9600. The latter number is the baud rate, which we will leave at it’s default value of 9600.

Look for the one with your Arduino name next to it.

You should see some messages displaying all the available serial ports on your machine.

Make sure your Arduino is plugged in, click the print message, then check the output console. This has one inlet which we can send our ‘voltage’ to. To do this in Max, we will be using the serial object. Now we can start passing values to the Arduino. Space is a seperator so must store each value Max is sending packets of information to the serial port Int value // Create a variable to store our incoming value So all the Arduino needs to do is check the port for values and pass it on to the pin out.Ĭonst int pin = 6 // Pin 6 = PWM 6 digital out Remember earlier how passing values 0-255 corresponds to our output voltage? We can send this number from Max via the serial COM port. To pass data from Max to Arduino, we will use the Serial COM port. Do the same for the ground on the Arduino.įor additional information on the RC Low Pass Filter, take a look at Moog’s Arpeggiator tutorial here. Connect a ground from any screw terminal on the Werkstatt to the negative side of the capacitor. It’ll be too noisy to just pass straight into our CV input, so we have to build a Low Pass Filter.įortunately this is really easy! Take one 10kΩ resistor and one 2.2μF capacitor and create the circuit below on your breadboard. However, this is not a true analog signal. This corresponds to our ‘voltage’ which from the Arduino is up to 5V+.

We can do this using the analogWrite function, which we will pass a value between 0-255. This emulates voltage change by changing the duty cycle. To send out our analog signal, we’ll be using the Arduino’s PWM signal output.

Arduino Microcontroller – I used an Uno.

To begin, we’ll need the following things: In this project, we’ll use Max (or Pd!) to send voltages via our Arduino to the oscillator pitch CV in on our Werkstatt. What better opportunity then, to unlock the Werkstatt by finding a way to link it to the world of Max MSP. The idea behind it is a simple analog monosynth, with some extra tidbits to open up possibilities for experimenters to tinker. It was a fantastic way to learn about synthesis and capture that signature Moog sound at an affordable price. A few years ago, I picked up the Moog Werkstatt.
