This project is for a fully functional cycling computer built from an Arduino and various sensors. Designed to connect to an Android device over bluetooth via this app:
- Wheel RPM
- Odometer
- Front/Rear Gear Indicator
- Low power consumption (about 30 hrs of use from 4x AA batteries)
- Brake light control (MOSFET switching external power supply driving LED board)
- Brake sensors (Bump switches on brake levers?)
- Dynamic configuration via Android app (store settings in EEPROM)
- Automatic shifting
- Switch to Arduino Pro Micro (to reduce size and power consumption)
- Arduino Uno
- HC-05 Bluetooth module
- A3144 Hall effect sensor
- 1/4in Neodymium magnet (additional magnets optional)
- 10k Slide potentiometers (45mm travel) (x2)
- 4xAA Battery holder w/ DC barrel jack
- 20+ ft 22AWG wire
