Summary of SPI Interfaces using Arduino
This article presents an Arduino tutorial on controlling LED brightness using SPI communication and the AD5204 Digital Potentiometer. It provides a downloadable parts list, software links for programming and circuit design, and references to related projects involving SPI devices like RGB LED matrices.
Parts used in the SPI Device Control Project:
- Arduino Uno
- USB Cable
- Arduino Software
- Eagle CAD Software
- Breadboard
- LEDs
- 220 ohm Resistor
- 10k ohm Resistor
- AD5204 Digital Pot
- Jumper Kit

Thanks to Jeremy , for this articles
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!
