The Arduino was one of our main electronic components for our project. We used the Arduino to turn the motors on when the button is pressed. Which basically helped with running our whole massage system. We initially attempted to use a micr0-arduino, but found that to provide sufficient power to our motors we would need one that supported a higher voltage.
The breadboard was also a key component for our project since that is what we used to connect all the different components. Initially, we tried to use a mini bread board but found that the right and left sides of the board were not connected by copper strips underneath like the regular one is, so to wire both motors, the battery pack, and the button on one board was much simpler on a full-sized breadboard.
Our motors were also a key component of our project, since they were used to actually rotate our massage rollers. We used two motors to provide the most efficient massage.
