Assembling an interactive timer for entrepreneurship workshop pitches
Problem description
In entrepreneurship workshops, students need a system that helps them manage the time of their presentations (pitches). A visual and auditory timer would facilitate time control without requiring manual intervention from a teacher or judge.
Problem solution
An interactive timer with sensors and an alarm that students can easily activate and that visually indicates the remaining time using color-changing lights. It will be activated via a button or proximity sensor and will alert when time is running out
Technical features
1. Structure and Design
- Enclosure made with laser-cut acrylic or 3D printed plastic
- Compact size for placement on tables or podiums
- Possible use of transparent acrylic for lighting effects
2. ELectronics and Sensors
- ESP32 ir similar microcontroller, due to its connectivity and flexibility
- Proximity sensor or touch button for activation
- RGB LED strip that changes color based on the remaining time: Green for the start of the pitch, yellow for the last minute and red when the time's up
- Buzzer or small speaker for sound effects
3. Programming
- Use of Arduino IDE or MicroPython to program the countdown
- Configurable time settings (ex. 3, 5 or 7 minutes)
- Manual reset option
4. Integration and Testing
- Assembly of electronic components on a custom PCB designed in KiCad
- Time accuracy tests and sensor adjustments
- Validation with students to optimize usability
