A turn angle detection sensor is used to detect the exact measure of turn of the bike handlebar. This angle measurement is used to determine if the bike is taking turns. This sensor design has two different approaches. These are varying resistance approach and hall effect approach. Finally, we settled on using thinpot which works on the varying resistance approach. These two methods are explained below.

Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Turn Angle Detection Sensor

Hardware Design

A turn angle detection sensor is used to detect the exact measure of turn of the bike handlebar. This angle measurement is used to determine if the bike is taking turns. This sensor design has two different approaches. These are varying resistance approach and hall effect approach. Finally, we settled on using thinpot which works on the varying resistance approach. These two methods are explained below.

Varying Resistance Sensor
This sensor functions using the principle of Ohm's law. This law dictates that the current is inversely proportional to resistance for a given voltage. The sensor has three terminals, two end points for connecting voltage across sensor and one middle terminal called wiper. As the wiper terminal traverse over the coil, sensor gives varying resistance across wiper and one of the other terminals and hence varying voltage. Varying voltage output pin is connected to the ADC of the micro-controller and exact turn angle can be determined.

Software Design & Implementation

For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.


Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
