Next Steps
Ideally in the next iterations;
1. 6 NeoPixel would be more attractive, especially if they can influence each other;
2. Offer the function to customize the music to users' taste;
3.Build a beautiful container to cover the whole device and disguise the FSR sensor into something users would like to touch frequently, such as a leave or a waving hand;
4. Do some research on material. How transparent, semi-transparent or craved figures can offer diverse light effects.
