I recently graduated from Cal Poly San Luis Obispo with a degree in Electrical Engineering. My interests include electronics, embedded systems, and software. I created this site to share my projects and ideas with YOU. Thanks for stopping by.
I recently connected an Arduino to a Tri-Color LED Light Bar that I bought from SparkFun Electronics. I used pulse width modulation to control the brightness of each color. The individual colors combine to make the desired color. Download the code here and see the schematic below. Read more »
I have wanted to build a project with LEDs for a long time. This weekend I came up with an idea, an LED coffee table.
The table would have a large compartment in the center to house the electronics and either a clear or translucent top to allow the light to shine through. Ideally I would use a combination of red, green, and blue LEDs connected to a microcontroller. This would enable the table to fade in and out of different colors. However, the design could be greatly simplified by choosing a single color LED and hard-wiring it to a power source, excluding the microcontroller altogether.
