Introduction: We are building an automatic bike transmission that will switch gears based on a mix of rpm and angle of elevation.


Background Research: These have been in development for over 50 years, although the technology is not perfected and still expensive. The computer is constantly trying to find an optimal combination of front gear and back gear in order to keep the rider at a constant rate. We want to streamline this process to help the user have a gentler suspension.


Details: Arduino to control, either a Servo or piston to switch gears based on input from encoder / gyroscope.


Parts: Arduino, Servo, Bike, Cadence Meter, Magnet, Casing for Electronics


Possible Challenges: Working with both the front and the rear gear will be expensive and hard. The actual switching mechanism will be hard as well, outputting to the motor requires experience. The coding should not be that hard.

Please include which course everyone is in at the top of your page.

Additionally, I would like to see a bit more information about how you will mechanically connect your device to the bike. Have you though about which accelerometer you're going to use?

You need a block diagram for your project. You must specify the components involved, how they communicate and how they are connected, and what purpose each component serves.
