INTRODUCTION

Project Description

This bicycle security system includes a speeding warning alarm and a vibration alarm that alarm rider according to the circumstances of the road. We intend to use an accelerometer to determine the condition of the road and a bicycle computer to read the speed. We set different speed limit according to the road condition and if exceeding the limit, the system warns the rider to lower the speed.

Operating Logic

Potential Challenges

1. It is difficult to find the relationship between the information sent by Accelerometer and the real road condition.
2. How to construct the function to determine the speed limit with different road conditions.

Parts

1.Triple Axis Accelerometer https://www.sparkfun.com/products/13926 

2.Hall effect sensor

3.Speaker

4.Arduino 

5.LED Screen
