A little teaser

Got some basic functionality out of them. Right now they’re all flashing the same color on each pulse. They have to be randomized. That’s an easy fix to make. In order to make the device detect that we it is currently moving I simply store the current accelerometer value in an instance variable for the next loop and grab a local variable that updates at every cycle. I then compare them and see what the difference is. If that is greater than a threshold I define then the device will register that it is moving. However, there is one flaw with this design. If the dancer is moving at a fairly constant rate, the device will register that as them not moving, since it is detecting acceleration in a direction, not velocity. So only changes in velocity will be registered. A little bit of physics to remember in case this blinks at a weird time. At the beginning of the video the LEDs are twinkling. This is the setting it defaults to when the accelerometer check does not detect any movement. Those need to be white, not colored. Another easy fix to make.
