This is the party trick that ends the party. The alarm clock for your siblings that earns you a wedgie. This is THE MOST ANNOYING SOUND IN THE WORLD. It truly is. And it’s annoying to difficulty ratio is wonderful. Oh yeah, and it’s all because of science.
If you’re feeling too un-annoyed today, start with the video to listen in. Then imagine that at about ten times the volume right next to you. And then get a can and do it yourself! You’ll be the life of the one-person party you’ve suddenly created. 🙂
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.
