Our junior design project consisted of a custom countdown timer. This timer had different features including a 7-Segment screen, power switch, 5 buttons of adjustment and a custom 3D printed housing. We used an Arduino Uno microcontroller to handle all input and outputs of the timer. The Seven Segment display we used was the TM1637. This only took two inputs to control making the coding much simpler. One success we had was our housing created for the timer. A lot of careful measurements and creative thinking allowed us to create a protective and eye-catching design. The challenges of the project were thinking ahead. We tackled challenges as we hit them instead of planning ahead possibly avoiding some issues.
