This is my first installment in the BONUS series where I'm tapping into the turntable's audio spectrum data that I'm publishing on the internet.

light organ loads of leds

 

My first bonus design is a remote light organ. I'm building it with an Arduino Yún, the Infineon RGB Led Shield and a bunch of LEDs.

Part 1 is my log on the build, and trying out if the Arduino-to-Infineon-toLEDs works.

 

Re-use and Re-purpose

 

I have kind of a head start here. For a previous element14 event, I have been using the RGB shield before.

That enabled me to just pull up the sketch that I used back then.

(I'll be able to do the same when building an MQTT listener on the Yun - been there done that.)

 

 

It's been a day of old school electronics. I pulled out the trusty soldering iron from my school days and did some trough-hole work.

The remote organ will fit in a little shoe box, so I cut out a plate of carton to mount everything on.

I've connected the things up and tidied the layout a bit.

Sketch loaded - and it works. At the moment it's animating each of the 3 rows in 4 intensities.

That 'll change in part 2, where I'll tap into the MQTT data and turn this into a light organ.
