Explaining about the i2c protocol and different devices

A short video about different i2c devices that I have connected to the Raspberry PI and created services for. I'm using them in my InMoov robot build http://www.inmoov.fr and the software that I'm using is MyRobotLab http://www.myrobotlab.org I2c is a simple serial protocol that allows you to connect and address many different devices on the same two wires. The reason that I'm doing this is that I want to put more sensors into the robot that I'm building, and the number of cables increases for every new sensor. But with i2c I can keep the number of cables down to a minimum, without being limited in how many sensors I can use.
