projects on arduino , autopilot and SPI & Sensor support for Python

Hello ,

Can anyone guide me on getting started with projects on arduino , ardupilot and SPI and sensors for Python.
I have worked with the Arduino UNO , MEGA and Leonardo boards as Embedded Hardware Design course objective. Also I have acquaintance with ardupilot and arducopter(used them for software monitoring of the quadcopter).

I am a student of International Institute of Information Technology and currently midway my 4th semester.
Preferably really keen on getting involved in core hardware projects and open source contributing.

Many thanks.
