The experiment by simulation of wind speed from the engine and blades with the co-ordinates of the wind speed from 0–6 m/s. The experiment has two formats, by the first method is experiment of wind speed constant at 3 m/s, 4 m/s and 6 m/s. And the second method is experiment of wind speed variation at 3 – 6 m/s. The experiment is period of time in 1 minute, 2 minutes and 3 minutes. By experiments in each method will trial start wind turbine and do not start wind turbine trial at 5 times and then and then apply the value that is saved in the the SD card to write a Graph for comparison, and to simulate flow of the air by using a program
