What if Guitar Hero was real? I built a one-hand guitar mode with ESP32
I’ve been working on a guitar robot project that can physically play a real guitar.
This is a test of a new “one-hand mode”.
Instead of fully automated playing:
- The left hand (fretting) is handled by servos (ESP32 controlled)
- The right hand is played by a human, following visual cues on a phone
So it becomes something like a real-world rhythm game —
but you're actually playing a real guitar.
No MIDI, no speakers.
All sound comes from real strings.
The goal is not playback, but physical performance.
Still working on:
- timing precision
- dynamics (strong/weak picking)
- servo noise & damping
Curious what you think —
Does this make guitar more accessible, or does it feel too “robotic”?
