A few months ago I modified a vintage Casio synthesizer so that it could produce bizarre new sounds. At the same time, I built an interface that allowed an Arduino Mega microcontroller to control the keyboard. This was part of my scheme to use electronic assistance to solve my ongoing problem of not actually being able to play any instrument.
Initially I programmed the Mega simply to play a stored melody. I could have bought and retrofitted a MIDI (Musical Instrument Digital Interface) for such a task, but I used a Mega because I wanted greater flexibility. In particular, I wanted to be able to hook up different sensors and translate their readings into musical notes. So when the makers of the TeraRanger One—a US $140 range-finder sensor—sent me a sample unit, the wheels in my head started turning.
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
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.
