I have been wanting to play with the MSGEQ7 that Sparkfun sells. The MSGEQ7 is a graphic equalizer display filter that splits the audio into 7 bands and outputs via an analog signal. So in my last order, I decided to toss in the SFE shield with the MSGEQ7. This shield is all ready to go and it can analyze right and left audio channels. I am using it with a Arduino Leonardo.

The kit comes with everything you need, just add …

Well I wanted to share some photos of how it turned out. My best friend and also best man, Warren, was able to help build an enclosure for the LED Matrix display before the wedding.

Sparkfun ISP Pogo Adapter

Each Friday, Sparkfun uploads a new video showcasing some of their recent products. One of June 28th’s new products was an ISP adapter that uses Pogo pins. This is great for programming multiple boards or if you just want to load the boot loader without soldering headers. I couldn’t pass it up as I program many boards without soldering headers. By the following week I had the kit in hands, ready to solder up! This kit is great. It’s easy to solder together by following the SFE assembly video. Here are a couple of pictures of me assembling. You can pick one up here:, at a great price. It’s definitely worth it!
