Beginner-Friendly DIY Conductive Touch Instrument Kit (e.g., Fruit Piano)
The 'Banana Piano' project is a fun and engaging Arduino creation. Comments like "I need to know how it's working" and the overall positive feedback show that there's genuine interest from people who might want to try something similar but may not have the expertise to gather parts and write code from scratch. This opens up an opportunity for a physical product: a 'DIY Fruit Piano Kit' or, more broadly, a 'Conductive Touch Instrument Kit' for beginners. The kit could include an Arduino-compatible board, necessary sensors and wires, and very clear instructions with example code. It would provide an educational and entertaining entry point into electronics and programming for hobbyists and students.

Hello this is my 3rd project ever and enjoy playing around with the ardunio (: Let me know what project to do next.

How big is it? What do we use for a scale?!
u/RoboDIYer
Really cool project! I love it
u/abagofcells
My only complaint is that you didn't use banana plugs.
u/Unlucky_Iron6831
Yup just any fruit that conducts 🤣 although I could change the sensor outputs for each different fruit that’s a cool idea (:
u/kwillich
Haven't we done enough harm to nature????

Wow your third project is already this great.
I need to know how it's working because I only see one wire in each banana, are you grounded to the arduino?

Love it! Guess you need just something that conducts? Does it change when you mix fruits/vegetables?
u/Unlucky_Iron6831
Hmmm nana for scale?
u/Unlucky_Iron6831
Yes grounded to the ardunio I can post the code once I’m off work (:

Is it polyphonic?

I didn’t know that’s possible 😂😂😂

I've heard of bananas for scale, but you can practice scales on you bananas
u/siddu_s
What module is used here ?

Obviously the next step is to play the Beverly Hills Cop theme on this. It’s what I do with every weird instrument I make
