Using Arduino with VVVV now is easier than ever

VVVV is an open-source software toolkit supporting interaction designers and artists handling of large media environments with physical interfaces, real-time motion graphics, audio and video that can interact with many users simultaneously.

The cool thing is that you can control Arduino and Genuino boards with VVVV by uploading a Firmata sketch and then start playing with the input and output pins.

What’s more, the team recently released a brand new set of nodes able to talk to your Arduinos. With this implementation you can:

  • Just plug a DigitalWrite (Firmata), AnalogWrite (Firmata) or ServoWrite (Firmata) node to the Arduino node (or concatenate them together) to set the pins of the Board.
  • Connect DigitalRead (Firmata) and AnalogRead (Firmata) nodes to get the values from the Board’s pins.
  • Use the Sysex Messages output to receive different ‘Sysex Messages’ sent back by the Arduino Board. Some Sysex decoders are already there (see StringDecoder (Firmata), CapabilityDecoder (Firmata)). Sending custom ‘Sysex Messages’ is easy as well.
  • Your board is not listed in the NodeBrowser? The Arduino nodes are easily adaptable for other controllers running Firmata. Hello teensy…

Easier than ever before:

  • no need to supply a spread for all 20 pins and then SetSlice some of them to particular values.
  • no need to define the ‘PinMode’ for each pin.
  • no need to define which pins should report their values back.

Staging Beckett with 11 motors and Arduino Mega

Happy Days is an installation inspired by the work of the Irish avant-garde novelist Samuel Beckett who wrote the namesake play in two acts in the 60s. Designer and visual artist Irena Kukric created it in collaboration with Canny Sutanto and the aim of exploring narrative in the form of an installation. The five-minute play is staged using ten servo motors and a DC motor with an Arduino Mega and VVVV live programming environment:

We were beginners with Arduino and motors so we started out pretty basic, trying to move several motors at once. We decided to use VVVV platform in addition when we realized we needed a timeline for our script for the play. With this timeline, it was easier to deal with details such as when we want to move which motor under which angle and such. For beginners with coding, this visual programming environment is very approachable and the entrance level is much lower.

It is easier and faster to get to your desired outcome. What is great about VVVV and Arduino is that there is the Firmata library that enables you to work with both platforms in conjunction so even artists and designers with lower level coding skills are able to go from concept to realization quite easy. We used Arduino Mega which was very convenient considering the number of our motors and the pins that Mega has to offer. After we had our final order of cables and pins, we even made our own shield for it.

The play was staged without human actors or conventional (verbal) dialogue  as performing a ritual in the play overshadows the performer, the object of the ritual can survive on its own. Therefore, they used these objects or rather props from the play and made them actors, animating them with motors, as you can see in the video below:

 

“Years”: Playing wood’s year rings

“Years” is an artwork created by Bartholomäus Traubeck that translates wood’s year rings into sound. The record player uses a system  that analyse tree’s years for their strength, thickness and rate of growth. This data are mapped to a scale defined by the overall appearance of the wood and serves as basis for a generative process that outputs piano music. The system is composed by arduino, ps eye, stepper motor for moving the tonearm, vvvv and ableton live, all connected via midiyoke and/or serial.
