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:
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
