The main objective of this project is to design and build an intelligent wind turbine.After presenting state of the art about the wind energy in the world and in Algeria and discussed wind turbines different structures and types, the advantages and disadvantages, and the various structures of the used generators in the first chapters, we posed the steps we followed to make our wind turbine starting with the blades then the other parts. To ensure that the turbine is always against the wind to get the maximum of the produced power, we added a yaw mechanism controlled with Arduino Uno.
