// I love this software hack! When using the Photon
// module (which is a Turtle which can draw lights on
// its path), the only way to turn the Turtle off is
// to reset the Circuit Playground. In order to
// prevent the user from doing this, I devised a
// method which uses the state of the microcontroller
// to set a variable which only invokes a reset when
// it has been set. When the bulb is disconnected from
// the base, a cool Photon animation plays, and a
// variable called "Must Reset" is set to 1. When the
// bulb connects to the base, we check for the state
// of "Must Reset" and if it is set to 1, then a
// different animation plays and a variable "Reset
// Photon" is set to 1. Now, on the next iteration we
// have a condition which checks if "Must Reset" and
// "Reset Photon" are each set to 1; if they are then
// the Circuit Playground resets. After the base
// resets, the code for the initial "on start" event
// is executed, and in this case we just set the LEDs
// to white at half brightness. Since "Must Reset" is
// no longer set (since the bulb is still in
// electrical contact with the base) we have
// successfully completed the state machine!
