Summary of SPI Interfaces using Arduino
This Arduino tutorial demonstrates controlling LED brightness through SPI communication using the Analog Devices AD5204 Digital Potentiometer. The project showcases how the Arduino Uno interfaces with the digital pot to adjust multiple LEDs' brightness. It references additional examples like Sparkfun RGB LED matrices and provides downloadable programs, schematics, and parts lists for hands-on learning.
Parts used in the SPI Device Control using Arduino:
- Arduino Uno
- USB Cable
- Arduino Software
- Eagle CAD Software
- Breadboard
- LEDs
- 220 ohm Resistor
- 10k ohm Resistor
- AD5204 Digital Potentiometer
- 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!
