Take it away, Paper-Duino!
Thanks to Sue P. for this one, highlighting the excellent work of one Wolfgang Spahn, a true Gadget Master. Check out his Paper-Duino-Pi, a Paper-PCB that serves as an Arduino shield for the Raspberry Pi…
Due to the fact that it is designed as Paper-PCB it is easy to create and one doesn’t need a printed circuit board. All components are standard electronic parts that are easily available at your favourite electronic shop. Plus they are really cheap. All you need are some electronic knowledge and soldering skills.
One can use the Arduino IDE running on the Raspberry Pi to upload programs on the Paper-Duino-Pi. Once you uploaded the Firmata* you have easy access to all the in- and outputs of the Arduino controlled by Pure Data, Python or Processing.
*Firmata is a protocol for communicating with microcontrollers like the Arduino from software on a host computer.
