I’m completely new to electronics and have just built Core Electronics’ Infinity Mirror V2 (Great kit and tutorial videos, I enjoyed making it!). I have a basic proficiency with programming and have been playing around with customisable modes.
I think it would be really cool to make the mirror somewhat responsive to sound, or in particular, to music. This may involve things such as:
Amplitude affecting the brightness within a mode
Tempo affecting speed/delay within a mode
Amplitude/tempo actually changing modes for you
Can anyone recommend a general method, and/or a microphone/sensor to do this?
The mirror uses an Adafruit Trinket 5V, as well as a potentiometer to select different light modes.
Thanks mate, appreciated the video and the information you shared!
I just had one more question if that’s okay – I need a little more understanding about the hardware components of this modification.
Do I purchase a VU meter/spectrometer or similar, and then solder it up to the Adafruit trinket in a particular way, and then the values will be readable after some particular coding and package installing? (I should be able to research this software aspect of it)
You could use something like this, which is a nifty little chip:
Which outputs a digital signal with pulse lengths that represent the amplitude of each band (by default, 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz). Here are a couple of pictures from the datasheet:
