I just finished my writeup for my Music Synthesizer kit project. The kit was made for a soldering workshop for the Boston University Artemis Project (http://www.bu.edu/lernet/artemis/), which is a Women In Technology Summer Program for rising high school freshmen. I work for the BU EDF (edf.bu.edu), which normally makes electronics for physics experiments, but we also do outreach electronics programs.
Normally the workshop would have contained a POV light toy, but we wanted a change of pace and I took lead to develop a music synthesizer with an 8 button keyboard, which can also act as a sequencer. There is a phototransistor which can pick up a light based message generated by this page, which my coworker Sam Damask made
Much of the hardware design for the DAC to Amplifier Interface was referenced from the Wave Shield; however, I made a bunch of changes to suit my particular situation and goals!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
