How to make a connection between an internet service and Arduino boards.

I created a Raspberry Pi face recognizer, which alarms me when somebody sits in front of my computer.

This tutorial shows you how to connect Raspberry Pi to CAN Bus (e.g. your car), explaining the role of each part and some recurrent errors.

When drawing on web, the drawing will be sent to XY plotter to re-draw it on bigger screen.

Set up some programmable festive tree lighting with Raspberry Pi, Fadecandy and Glediator software driving addressable RGB LED pixels.

Use Particle Mesh boards to collect data from all over a house. The data is then aggregated into the Particle Cloud.
