Damian Peckett has a great blog post that investigates how to detect the beat or tempo of music with an Arduino. Damian talks about a few different approaches using analog filters, simple digital thresholding, and more advanced detection in the frequency domain using Fourier analysis. Ultimately he settled on a few digital filters and thresholding to pick out the peaks of bass music thumps. Check out the post for more information and a few videos of it in action–great work!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
