![]() ![]() I recently published a video of my latest LEGO Rubik's Cube. Download the MindCub3r program to the EV3 (but do not runit yet). Find the MindCub3r-v1p4.ev3 project file and Open it. The download for the RGB color sensor block is available on David Gilday’s website: Check out my book, “Building Smart LEGO MINDSTORMS EV3 Robots,” available on Amazon: My Patreon supporters for more than $5 for the month of July were: Creator Academy, Robert Damiano, Al Douglas, and Executor Akamia. Start the LEGO MINDSTORMS EV3 software and select the File menu then Open Project. ![]() Find building instructions for the model, plus additional information and source code for the software on David Gildays webpage. Program The Lego Mindstorms Mindcuber Software On David. In today’s video, I will introduce the basics of RGB color, demonstrate programming with the RGB color sensor block, and make a simple program to detect the color orange. Program The Lego Mindstorms Mindcuber Software On David By adding a LEGO color sensor this model can solve a Rubiks cube. In reality, due to factors such as variations in ambient light intensity, this number is closer to 1000 distinct colors, which is still a massive improvement over the EV3 color sensor’s original range of 7 colors. This means that in theory, the RGB programming block will allow the EV3 color sensor to detect 16.8 million distinct colors. It works by scanning a color and reporting the relative red, green, and blue (R,G,B) light intensities, each on a scale from 0 to 255. The RGB color sensor block, invented by David Gilday, greatly expands the possible number of colors that the EV3 color sensor can detect. ![]()
