SPI Interfaces using Arduino
Update (6/7/2012) – I’ve had to disable comments on this post, because it is being targeted by spam bots for some reason. Please use the contact page if you have a question about this topic.
In this week’s arduino tutorial, we’ll be taking a look at SPI device control using the arduino. Specifically, we’re going to be using the Analog Devices 5204 Digital Potentiometer to control the brightness of several LEDs. For an example of another device that uses SPI control, checkout these Sparkfun RGB LED matrices that I’m using in my ReacXion Audio/Visual Theremin. Enjoy the video!
