Night Safety Bicycle: Mechatronics Design Project, Colorado State University


  • Designed and fabricated a system to generate power from the bicycle wheel’s motion to run a lighting system
  • Programmed a microcontroller to measure speed and distance traveled, detect light, and control an active LCD

The dynamic system allows for colors of wheels to be changed while riding with a photo sensor for automatically activating the system at nightfall
