Day 3

The group managed to incorporate the accelerometer into the project. Now, when the code runs if there is a car in tailgating range of you while you're slowing down, the lcd display will display a message of "I'm slowing down" or "Braking." The group can have it flash repeatedly the closer a vehicle is to you in order to emphasize the message. The code for the group project is now as follows:

          

Day 2

The group has begun working with the electronics portion of the project. The first task the group dealt with was displaying messages with an LCD display. This is shown in the following video and block of code.

The next hurdle that the group faced was utilizing the Parallex Ping sensor to determine distances. The following video and code shows how the group got the ping sensor functioning properly.

The last task of the day was to integrate the concepts of the both codes into one. The final result of this integration will display a message telling the object to "Back Off" as well as display the distance the object is from the sensor. The following video shows the circuit working as described and is accompanied by the code that allows it to function.

This concludes day 2 of our project.

Team Accident Awareness

Team Accident Awareness is a mechanical design lab team that will utilize a sensor to detect approaching vehicles from the rear end of a car. The sensor will run using arduino and a message will be displayed by an LED display telling the tailgater to "Slow Down" or "Back Off".

The team members consist of Jeffrey Cheng, Kristofer Tite, Samuel Kibirige, Eric Carey from left to right

Day 1: The team met to discuss the electronics portions of the projects. The team discussed potentially building an FM transmitter from scratch. The video below served as inspiration and the team would build it using the same parts.

The parts needed for the sensor are as follows: 18AWG solid Copper Wire, 1/4-20 bolt, copper-clad board, liquid adhesive, two 0.01 micro-farad ceramic disk capacitor, 25K ohm resistor, electrolytic capacitor, 10k ohm resistor, transistor, two 10 pico-farad ceramic disk capacitors, 470 ohm resistor, battery and appropriate tools.

Other topics discussed were the code and housing, A solidworks render of a portion of the housing is displayed below. The housing would be created from a clear plastic like Plexiglass.
