The project prompt challenged us to address a personal pet peeve while encouraging user interaction. For my solution, I chose to tackle the frustration of my roommates leaving their clothes in the dryer. To solve this, I designed an innovative alarm system that would only stop sounding once the laundry room door was opened, ensuring that the clothes were promptly removed and helping to maintain a more organized, considerate shared space.
I implemented this solution using a hall effect sensor to detect whether the door was closed, a piezo motion sensor to determine if the laundry was running, and a MIDI MP3 speaker to play the alarm. To prevent false triggers, I incorporated delays that allow the system to accurately determine whether the laundry is on or off, ensuring it won't be confused by accidental disruptions, such as the laundry being knocked or brief pauses in the cycle.
