Story
A small metronome shall be programmed with the Calliope mini. The current pulse is supposed to be put out via the LED array. Also an acoustic feedback is given: The first pulse of the clock creates a sound. The other pulses do not.
The clock rate can be varied using the buttons.
In standard mode, the metronome is designed for a four-four time signature. If pin P1 is pressed, then the metronome is set to a three-quarter time. If pin P0 is pressed, it switches back to a four-four time.
