A year ago i bought an adafruit Pi dish for my Raspberry Pi. It is very handy because it keeps secure in one place your Pi and if combined with a cobbler and a breadboard it is ready for your projects.
In my project Arduino Uno + Raspberry Pi + workout stepper. both Raspberry and Arduino where in a distance and i wanted to have them both side by side.
I manage to have them both at the same dish and each use half of the breadboard. You need only 1 plastic screw from the kit for each board. The screw for the Raspberry goes to the hole below the Raspberry Pi logo so you can turn in order to put the power supply.Also the screw for the Arduino goes to the hole next to your arduino logo.
