Video Beats uses a Propeller QuickStart board and a Quick Proto to sample line-level audio (like from your MP3 player) and generate video graphics. As the audio input changes, new graphics are generated to match the audio.
Seven visualizations are built-in, they will change automatically, or you can switch them manually by using the buttons on the QuickStart. You can also customize the visualizations to change colors or shapes.
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.
