Nate Rudolph's Midterm Journal Entry 1

I set out to create some sort of exercise tool with the pulse sensor. I’m still waiting on an accelerometer to begin piecing the project together, but I’ve begun the code and wiring diagrams to start sketching out how it will work.

These components will be fit inside a ball with the LEDs in a line following one axis. The goal of the object is for the user to orient the ball according to a set LED by tilting to make that LED face upward. The rate at which the LEDs change will be determined by the pulse sensor that it attached to the side of the ball.

My original concept was to implement this into a large weighted medicine ball, but as I sketched out a storyboard, I thought it would allow for a longer and more interesting interaction by having two hand held balls that interact with each other as the user progresses through the exercise.
