When listening to music in the lab, I wanted a way to visualize what I was hearing – creating my own artificial synesthesia. This latest project is a simple sound visualizer, what sound engineers might call a volume unit (VU) meter. There are three main parts to this project: the audio sensor (mic), the microcontroller, and the LEDs. After finishing the project, I mounted the strip on the back of my new adjustable desk with some velcro. I got all of the parts from Adafruit:
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.
