The folks at Tellart in Providence, RI made this awesome interactive automated bell ringing project, which they call the Love Song Machine. They write:
In celebration of Valentine’s Day, Tellart is launching the Love Song Machine, a musical instrument controlled (by you) through the internet. Visitors to the website can select a song or compose their own, and press play to send the song to the instrument in our Providence office.
The bells are played by a series of solenoids, which are controlled by an Arduino micro-controller. The notes that you submit are processed on our web servers and then sent to the Arduino, while we load up live video and audio so that you can watch your song play. If there are users ahead of you in line, the queuing system will let you know how long you’ve got before you can watch your song.
The bell machine will only be available for a limited time, so start composing!
It has a bunch of premade songs you can make it play, but it’s more fun to figure out your own, so I came up with the ostinato phrase (intro) and verse to Radiohead’s No Surprises:
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
