Arduino+Adafruit Audio FX Sound Board+Sound to Light- Animatronic Wheatley v2.0

[@riesupramp5207]

How did you get the arduino to communicate with the adafruit soundboard. I have mine connected and can communicate through serial monitor menu commands, but can configure the line code to work directly from the arduino via buttons or pir. Please help

Here's the link to my full work log: animatronicwheatley.com/wheatley-v2-0-work-log/ Use CTRL+F to search on the page for NPN and you'll find the schematic I came up with and the parts I used. Basically, I used 6 of the same transistor to make a switch that connects the output pins of the Arduino to the trigger pins of the Adafruit Sound Board. Make sure in your code that when you press a button it sets the output pin high, and that both boards share a common ground. Hope that helps!

Luke Albertson ok, I am doing mine differently. Since my bot will have a single motion sensor I have the arduino triggering a random track via serial. Depending on the track number, it will light the corresponding rgb color. Problem I am having is making the led pulse over pwm based on an analogread off of the audio freq.

So, having the LED flash to the sound like in my video?
