A great project the creates a MIDI controlled slide trombone. Here’s more from iSax Laboratories:
The original idea was to produce a MIDI controlled music machine that could play any song. It was however extremely difficult to control it reliably. When a human trombone player produces a tone it is a combination of lip tension, pressure against the mouthpiece, airflow, air pressure, resonance in the mouth and probably some other variables. The lip part proved too hard to recreate. The machines will not take over the trombone plying profession any time soon and I’m left with an over engineered noise machine.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
