CLASSIC COMFORT
“Merging the past with the present”
WORK PLAN
In this section we identify the work that needs to be done. We take a look at the project overall and
identify the main phases which will be associated with the project. By taking these phases and breaking
them down further into activates, tasks, and even subtasks, every aspect of the project can be
identified. The WBS for our project is divided into six phases. Figure 3 shows the phase level of the
Classic Comfort project. The phases for the completion of our project include Research, Hardware
Design, Software Design, Testing, Fabrication, and Documentation.

Research
Research will be conducted at the beginning of the project. It will be conducted mostly in
current limiting circuits, noise filtering, Painless wiring harnesses, microcontrollers, dual seven segment
displays, and size constraints.
Hardware Design
The basic hardware design of our product will include connection to most existing wiring
harnesses in classic cars and also full integration with Painless Performance wiring harnesses. Our design
will contain regulated power from the existing car battery connected through a protection circuit to the
microprocessor and dual seven segment display. We will also implement three current detections
circuits that will be connect to the headlight, door, and ignition switches to obtain the status of these
switches to be input to the microprocessor. The output of the microprocessor will then be connected
through an amplification circuit, to a particular function, i.e. headlight delay, radio delay, etc. which will
drive the function according to switch status and software design of the microprocessor.
Software Design
The software code will be written to command the microcontroller to perform various tasks.
Software codes will monitor the voltages and control timing and levels of voltage output from the
device. It is important that the software be robust, extensible, fault-tolerant, secure, and maintenance
must be easy. These goals will be met in the software design.
