Fitness Unit Wiki¶

Welcome to the Fitness Unit wiki page. The Fitness Unit helps monitor and track workouts. Capabilities include noting acceleration, counting reps, and timing exercises. The Fitness Unit has three main components:

• The Main Unit
• Tracking Unit
• Body Unit

Each of these components work together over a wireless internet connection to communicate and aggregate information.

Units¶

Each unit performs a vital task to the operation of the complete device and communicate together for end-user ease.

Main Unit¶

The Main Unit of the Fitness Unit allows the user to customize and monitor their exercise. A full-color LCD screen displays the total number of reps, a countdown of the current number, a timer, and messages. A knob changes the maximum number of reps desired and a button resets the timer. It acts as the central hub for the other two units in the Fitness Unit set.

Tracking Unit¶

The Tracking Unit uses a range finder to detect the distance the user is from the board. When the distance between the two is that of a proper press up, the unit gives both a visual and auditory indication when reps are being completed. The red LED screen counts down and a buzzer gives a notification sound, allowing the user to focus on the exercise, rather than checking how much they've done. When the countdown reaches zero, a message is scrolled across the screen.

Body Unit¶

The Body Unit is worn by the user and has an accelerometer attached. The accelerometer tracks the movement of the user in two directions and can also count down the number of reps. It can be used for a wide variety of exercises in addition to press-ups, such as running or squats.

Wireless Communication¶

The boards communicate over a wireless network. They send information through a router, with the Main Unit acting as a server.
