I'm a student of electrical engineering in Sumatera Island, Indonesia. Now, I'm in the last year of my study. Since in college, I have finished some big project with arduino, microcontroller, etc. In example, I have made a robot with the name Gebotc (Gesture robot vacuum cleaner). This robot is made with arduino, DC motor, wheel, and a Radio Frequency module. We can use Gebotc to clean our room. Gebotc use a laptop fan as a vacuum cleaner. And there are so many project like this I've done before. I think that's all from me. Best Regards, Fakhrur Rozi
