Raspberry Pi Pico Metronome (Potentiometer + TM1637 + Buzzer + LED)

Turn the knob and the tempo follows! We are building a 40-200 BPM metronome with a Raspberry Pi Pico. A potentiometer sets the tempo, and a TM1637 display shows the BPM plus a pendulum that swings on every beat. The buzzer plays a high click on the first beat of the bar and a lower one on the rest, while an LED flashes in time. After each change the display names the tempo: Largo, Adagio, Allegro and more.
