Cycle Navigation Aid – A Safer, Hands-Free Solution
Arduino – Based Navigation Device for Cyclists
NavBand is a compact navigation aid for urban cyclists, combining an 8×8 LED matrix display with a tactile vibration feedback system to provide clear, hands-free directional guidance. Designed to attach to a bicycle handlebar, it visually displays arrows for navigation (left, right, or straight) while distinct vibration patterns—one buzz for left, two for right, and a long buzz for straight—ensure cyclists can focus on the road.
Lightweight and powered by an Arduino microcontroller, NavBand is simple, affordable, and ideal for urban settings like Barcelona. By minimizing reliance on phones or screens, it reduces distractions and enhances safety for commuters and recreational riders alike.
NavBand is a practical solution for safer, smarter cycling in busy city environments.
“How does combining vibrations and LED cues improve navigation for cyclists?”
Hands-Free Safety : Vibrations keep hands on handlebars, reducing distractions.
Adaptable : Effective in diverse conditions like night rides or heavy traffic.
Enhanced Focus : Simple tactile and visual cues let cyclists concentrate on the road.
Dual Feedback : Vibrations work in any environment; LEDs reinforce clarity.
Accident Prevention : Minimizes risks from screen distractions.
User-Friendly : Inclusive for all riders, even those with sensory impairments.
Efficient Navigation : Directions are clear, intuitive, and easy to follow.

Arduino Code
In the first part of the code development, it was essential to test the sign display on the LED matrix. 3 push buttons added. Each button triggers a unique vibration pattern on the handlebar, providing tactile feedback so the rider knows the intended direction without needing to look. Additionally, the system displays the selected direction on an LED panel, ensuring clear visual guidance. This setup helps enhance safety and convenience for cyclists during their rides.
The second phase of the code development introduces a small map or predefined sequence of directions for the device. This feature enables the system to guide the cyclist along a specific route from point A to point B. The sequence includes programmed delays between directional commands, allowing the rider sufficient time to follow each step of the navigation smoothly. This addition enhances the device’s functionality by simulating real-world navigation scenarios.
