The PicoBoard was developed to communicate with the programming language Scratch. These days Sparkfun sells their own version of the popular educational platform.
The protocol is available on github and there’s a tutorial that walks through the Arduino code here.
We’ve made a Pd patch to bring in the data from the PicoBoard. This includes a button, 4 resistance sensors, light sensor, microphone and the slider.
Here’s what it looks like:
The download below also includes a demo file to make sound with the button, slider and light sensor.
