I was inspired by Kitty Yeung’s pattern-matching dress, and I wanted to do something clever for my daughter’s school dance party. I also had a limited amount of time, and a ready-made dress to use.
After some experimentation, I came up with an old-fashioned VU-Meter display, using the LED modules to colour code the output into a visually appealing, and recognisable display.
I liked the idea of the programmable LED modules, and I was able to get twenty of them in time. I had an Arduino Pro Micro module and a Duinotech microphone module. Because the code is very simple, you could use any Arduino device you have available, and there are many choices for the microphone module. The code also has a “random” mode which means you can do away with the microphone altogether and it looks just as spectacular.
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.
