This is an MSGEQ7 Arduino Tutorial and in it, we’re going to explore connecting the seven band graphic equalizer chip to an Arduino UNO R3 and start to get some measurable responses back. For those that have the MSGEQ7 Breakout Board, this is a great way to get started in understanding how to interface the chip with your own projects. Setup For this tutorial, you’ll need the MSGEQ7 Breakout Board, an Arduino UNO R3, some jumper wire, and some audio source connected with a normal headphone style cable, but that’s pretty much it. You’ll also want to download a copy of the datasheet for reference as well: Mixed Signal Integration MSGEQ7. The hook up for this doesn’t really merit a schematic, since the breakout board only means you have to hookup five pins, but for the sake of completeness, the schematic looks like this… Like I said, not much to it. Here it is all hooked up. The graphic equalizer chip manages the process of sampling and measuring the audio frequencies you provide it automa
