Connect your Raspberry Pi to the physical world

Add precise capacitive touch, distance sensing and high quality audio to your Raspberry Pi A+, B+, Zero and later (any Raspberry Pi with a 40 pin GPIO connector). Connect Electric Paint or anything conductive to one of the 12 electrodes to control sounds, video and more. Connecting the physical world to the digital world is easy with our fully featured libraries and our extensive online tutorials.

• High quality audio output
• Extensive tutorials and easy startup experience
• Powerful Python, C++ and Node.js libraries so that you can include sensors in your project
• User-programmable RGB LED and multi function button
• Prototyping area with GPIO breakout to add additional sensors or buttons
• Works with Raspberry Pi A+, B+, Zero and later (Any Raspberry Pi with a 40 pin GPIO connector)

The Pi Cap software is in the official Raspbian repository, so installing all the software you need is as easy as Pi. This also means you’ll get updates through apt-get, just like you do with the core Raspberry Pi packages. We love Linux!

Getting started with the Pi Cap

We have worked hard to make setting up your Pi Cap as straightforward as possible, whether you’re using a Pi Zero, Raspberry Pi 1 A+/B+, Raspberry Pi 2 or Raspberry Pi 3 our easy-to-follow instructions should help you get started.

Pi Cap Intro

The Pi Cap features tour walks you through the code examples that are supported by the Pi Cap library to give you an easy start to your project. Featured code examples include:

• Simple Touch – Get data from the Pi Cap showing which electrode has been touched or released
• Datastream-tty – Similar to simple-touch, datastream-tty continuously streams the electrode data
• Datastream-osc – Similar to datastream-tty, but streams OSC packets to a specified host over a network
• Polyphonic Touch MP3 – This example plays mp3 tracks in the tracks folder when electrodes are touched
• Text to Speech – Text files are synthesised (read out) by a computerised voice when you touch electrodes
• Button Utility – A single button press to prints Hello World! to the console, a double press reboots and a long press does a proper shutdown (avoiding corrupting your microSD card)
• LED colour spinner -Display code status, debug or start a tiny rave. Example code loops through a variety of colours – the source code shows you how to manipulate the LED colour.
