Overall, I am really satisfied with what I created for this project. It can successfully solve my trouble of choosing which lipstick to use in the morning and make my day starts with surprise and fun lol. As an architecture student, it was not a hard part for me to build a model in both digital and physical ways and do laser cutting. The most difficult thing for me is writing the code to make my device work. It was my first time writing the code independently which made me get a deeper understanding of the logic of each step. Thanks to Zach, he explained how to turn the lights on in order and taught me how to do the random choosing process. He was so patient and encouraged me a lot which made me become confident with learning the coding language. Also, I got a better understanding of the loop function which made the LCD display show the information incorrect time.<\/p>\n
I really enjoyed the discussion about the prototype with my classmates. They were so kind that gave me a bunch of encouragement as well as a lot of suggestions. For instance, someone suggested that I could use some tools to make the choice of lipstick based on the eye shadow I wear. I did think it is a good idea, a sensor can detect the color of eye shadow which could bring about a specific lipstick matching with all the makeup look. But what I want for the lipstick container is a totally surprising thing, you would not know any hints about which one to use before you tap the screen. A boy told me that I could add a screen to the container with some warm-hearted words on it. This suggestion was super useful so I add \u2018You Look so Nice Today\u2019 when finishing the choosing process.<\/p>\n
If I had more time, I would add a power switch to the container to make it work only when I need it. Also, I would think about developing another type of container like the girl\u2019s idea about matching with eye shadow. I truly think it will be cool and get in touch with many other interesting sensors and improve my coding abilities as well. Due to the limited time and energy, I could not complete all the good ideas so perfectly. I am really looking forward to the next project! I love new challenges and I believe, the new project will bring me a lot of inspiring thoughts and much more improvement about my abilities.<\/p>\n
