This is an ideal project for a science fair etc. – it’s not too difficult to construct, yet makes a playful interactive exhibit.
The idea is to have a lot of proximity sensors – each triggering a different sound sample. No touch needed – no complex light-beams etc – everything is just sitting on the one table.
The distance someone needs be from the table for a note is triggered is customisable.
It has an custom optimized ultrasonic code for sampling multiple detectors at once – it is highly responsive and does not block for seconds like the standard libraries tend to do when objects are far away.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
