Play table

Using proximity sensors for playing midi tones combined with LED visualization Description The aim of this project was to create a table sized device with multiple proximity sensors that can play midi tones. Each sensor had a few LEDs to show hand distance above the table. This table could be used by one or more persons at once. Hardware setup First I created a prototype from a cardboard to test sensors and some logic behind. Than I ordered a customized plottered sticker with a design which was painted with bare conductive paint. Afterwards I drilled some holes and connected the touchboard with 7 arduino Nanos. Each arduino was connected to 13 LEDs diodes. At the end I added two potentiometers. One for controlling volume and one for changing notes setup. Programming Programming consists of two parts. Master(touchboard) program that reads values from proximity sensors and sends messages to slaves(arduinos). Second program for slaves that reads messages from m
