Inspiration

Cyclists always get the shorthand of the stick when travelling on roadways alongside cars. Hundreds of cyclists find themselves in car-related accidents every day, and even our beloved friend found himself in a serious crash several months ago. By installing more features and functionalities to bicycles, we can significantly reduce the dangers of cycling on roads and make prioritize bike safety for our customers.

What it does

Functionalities such as night lights, brake lights, turning signals, and an information monitor were added so that cyclists can safely use lights around their bike to communicate with nearby cars. Motorists often find cyclists unpredictable, however this problem can be eliminated with this signaling system.

How we built it

Two Arduinos were used, one for the LCD screen and temperature sensor, and the second one for the LED signaling system. Two buttons were placed on the handlebars to activate the signal lights, a flex sensor was placed on the brake lever to trigger the brake lights, and the LCD screen displayed the temperature of the environment.

Challenges we ran into

Library problems for certain components, wiring issues, linking both Arduinos together, and mounting all these components onto a bike with limited resources.

Accomplishments that we're proud of

A final functional product that works and looks organized. We made something that could be mass produced for very cheap (We estimate the entire system would cost less than $4 to manufacture), overcoming the immense cost of current smart bikes ($1000+) in the market right now. Also, this system can be very modular and be compatible with ANY bike.

What we learned

More C, Arduino functionalities, sensor usage, Arduino linking, wire management and efficiency.

What's next for The LytByke

• More features such as blind spot monitoring that can notify the cyclist of approaching vehicles
• Phone connectivity (Bluetooth)
• Google Maps API for navigation directions that can be displayed on the LCD screen
• Condense the system and create a better infrastructure to support the electronics
• Make the blinking LEDs work on an analog system instead of relying on the arduino
• More environmentally friendly with pedal powered systems.
