Process

• My project went through multiple changes towards the end. At first, I wanted to build a fan that would turn away from the user. I spent most of the class time exploring and integrating different parts of my project. I focused first on being able to use and detect values from the proximity sensor, then on using the servo motor. I then wanted to try and build a physical casing for both of these components so that the servo could hold the fan up and turn it away, and spent considerable time doing this to no avail. I then instead focused on integrating the sensor and the servo by having the servo turn every time the sensor was read, which was successful. At this point, I decided to build my self-destructive fan, but I ended up breaking too many blades while trying to figure out how to consistently stop the fan. In order to have a working fan, I decided to change my project vision to instead just turn the fan off. As a result, I had to use the servo as a way to click the fan’s button. Most of the final parts of this process was spent building the hardware/physical component of my prototype so that I could combine all of the parts. From a software side, I was able to pull example code for both the proximity sensor and the servo motor. Since I have prior Arduino programming experience and since the project isn’t incredibly complex, writing the code was easier and faster to do at the end when I integrated everything. My final code is in the appendix.
