Bike Odometer and Speedometer – Schematic

For the Hardware portion of the prototype, we used a variety of objects.The largest of these was a standard bicycle that we used as a base for the odometer and the speedometer to sit upon. Next we used two breadboards to start, however this was later slimed to one breadboard to hold the wiring and transistors for the project. We also used an ATMEGA328P Xplained mini board to process the inputs and outputs we needed for the project. Miscellaneous electrical components include some resistors, wires, potentiometer, an LED display and a capacitor. The most unique component used would be the Hall effect sensor, which is in layman’s term a magnet sensor. As a magnetic field gets in range of the sensor, the total output voltage of the Hall effect will be changed due to the strength of said field.
