Processing demo code that shows how to upload an image from Processing to a web server. It takes a picture with your webcam and saves the image to a folder on your webserver with PHP.
In this article I explain how to you can control the GPIO pins of the Particle Photon with Direct Memory Access. This makes it for example easy to drive LED strips without any CPU cost.
I needed to add some illustrative pictures to a blog article and I wanted to give proper credit to the photographers and link to their websites. I didn’t found a proper plugin that I liked so I created this solution.
Demonstration of the raw Robert Penner easing functions implemented in the Ani library for Processing.
In this demo we use local communication to communicate with the Photon. This is a lot faster then communication through the Particle Cloud. Sending a message takes about 20ms instead of 300ms (and thats the timing of the Particle function and excluded the timing of passing the variable for the color).
