cap of cup with hole
thingiverse
This is a custom lid for an 180ml cup with a hole. The small-sized paper cup used comes from McDonald's, measuring approximately 80oz. A significant aspect of this project is the purpose behind creating this unique lid: connecting it to the color-changing lamp from Rose, which can be operated using Arduino. Furthermore, the same hole allows for normal usage - placing a straw in it. In a separate experiment, I created and demonstrated the rose-shaped LED lamp with 3 changing colors. I downloaded an STL file for a rose from Thingiverse (project: #212281). With that done, it's time to integrate the ultrasonic sensor and witness how the color-changing process responds when measuring distances.
