“In my first Instructable I’m going to go through the steps needed to create Water Speakers that act as an equalizer.
Water speakers from the store are great to watch, but I felt they could do more. so many years ago I had modified a set to show the frequency of music playing. At the time I used the Color Organ Triple Deluxe II, combined with a set of photos cells potentiometers and transistors I was able to get a set of 3 speakers to function.
I then a few years ago had heard about the IC MSGEQ7 which has the ability to separate audio into 7 data values for an arduino to read. I utilize an arduino mega 2560 in this project because it has the required number of PWM pins to drive five water towers.
This project uses soldering skills on a perfboard, Bluetooth module, arduino, and off the shelf water speakers. Through out the project I actually notice a few things that I should have done different so I’ll be sure to point them out.
Let’s get started”
