Build an affordable color mixer box for photography | Arduino Blog
Lighting is the single most important factor when it comes to capturing good photos. For a conventional setup, you probably want diffuse, indirect light in a natural color. But you can get more creative with the use of colored light. RGB box lights let you set whatever hue you want, but they aren’t cheap. Arnov Sharma’s color mixer box is both affordable and versatile.
This is a relatively small light box and so it alone isn’t suitable for lighting an entire scene, unless you want a dark and moody feel. But it is perfect for adding colored highlights or illuminating small objects in close-up photos. Three knobs let you adjust the color channels, so you can dial in the exact hue you want. An OLED display shows each channel’s set brightness and that makes it easy to reproduce colors that you set in the past. Power can come from either a USB cable or a battery pack.

Being a PLC engineer just became a lot easier! | Arduino Blog
With the demand for PLC programming rising due to the spread of automation in a wide range of industrial fields, we felt we had to step up for our community of budding and experienced engineers!
That’s why we have just launched a dedicated Arduino PLC IDE, which supports the five languages defined by the IEC 61131-3 standard: Ladder Diagram, Functional Block Diagram, Structured Text, Sequential Function Chart and Instruction List.
