The dartboard was provided by roommate from last year who was upgrading. This board was used extensively last year, but had not been used much the last few months. Included with the dartboard was the pressure sensor map and corresponding connectors. The microcontroller, breadboards, wires, electric components, push buttons, crystal and jumper leads were all provided by the ECE 476 lab. The TV was also part of the lab, but the final design can be plugged into any television and is not really part of the cost of design or implementation. The only purchase was for the batteries.

Most of the tasks were completed by both members of the team, the Owner is the person responsibly for the proper functionality of that component. Most of the testing was carried out during design, however rigorous testing was done at the end of each design stage to ensure complete operation with all components under all circumstances.
