The story

Fruit Decoder

What if dragon fruits could make music?

Three dragon fruits were connected to an ESP32 and turned into touch sensors. When touched, each fruit changes its capacitance, which is detected by a Python program.

Each fruit triggers a different sound, turning three dragon fruits into a mini musical instrument!

What the sources say

The idea is technically supported, but independent coverage of this exact project is limited.
