Stepper one is an STM32-based belt-clip pedometer featuring:
- Custom PCB
- E-paper display
- Side-mounted buttons
- Acrylic light diffuser
- EEPROM emulation
As part of my university subject 41070 Embedded Mechatronic Studio, groups were given 12 weeks to design a pedometer - PCB, housing, software, and all. My team had the honour of presenting the device at the 2025 UTS Tech Fest Robotics Showcase, and it received Runner Up of the 41070 Embedded Mechatronics Studio Innovation Award.
