I enjoy singing in a choir as a hobby.
Sometimes, instead of piano accompaniment, we sing along to a recorded track with a fixed tempo.
In such cases, we sing along with the recorded track, but depending on the situation (such as when singing at a performance venue), our voices can drown out the recorded track, making it almost inaudible.
This can lead to serious mistakes. Such situations occur frequently.
Therefore, I thought it would be useful to have a metronome that is not noticeable to the audience when using a fixed-tempo recording.
In small ensemble choirs, we synchronize the tempo with eye contact, but it works well if one person can maintain a steady rhythm.
The leader carries this device discreetly and guides everyone.
A tempo keeper in your pocket!
• Pressing the A button on the M5Stack Core2 allows you to start/stop the metronome.
The tempo is displayed via a buzzer sound, LED, and vibration.
The vibration function allows you to check the tempo in your pocket without being drowned out by surrounding noise!
• Tempo changes are made using the B and C buttons.
Environment setup methodSimply write code using Arduino IDE on M5Stack Core2.
