  • Hey I’m a bit confused, if I want to control each LED’s color and brightness individually (ie “analog”) via an arduino how do I set up the resistors with the matrix? I understand in principal how the matrix works from reading the linked article, and it makes sense for the switches, but I want to do more than binary on/off for the LED’s.

    I got the breakout boards for the TLC5940, I would just control the LED’s individually in that case right? (ie switches connected to the matrix pads on the outside of the board, and the LED’s connected directly from the board)

  • just a heads up, if you’re trying to do anything with audio sampling/delay type effects without much effort/extra circuitry you should check out the audio hacker shield from nootropic design. The audio quality is lower, but not unusably so. The Maple (which this has libraries for) is also very difficult to use on Windows. I guess the bottomline is to research before you purchase either.

  • Would love to use this board, but as mentioned below, it is a pain to set up on Windows. I’m on Windows 8 and I couldn’t get it running last night, was using it with the audio codec shield (there is a looper pedal example with the maple native that made me think to get the maple in the first place), but was up and running on the arduino in 5 minutes. Bummer.

  • Hey I just want to confirm that this makes sense. I’d like to measure the intensity of pinching a small (squishy, cast rubber) object. Doesn’t need to be accurate, just not digital (ie range from 0-10 vs 0/1). You’d still be able to get a reading from being placed inside a small object depending on the force applied and amount of quality of material correct?
