Please read the guidelines! GUIDELINES Type the number, name and theme of the model (I prefer Brickset themes) at the top of your post. This topic only makes sense if you give a link to your model, so other people can download it Put a picture of the virtual model in your post. Say if there are errors, if there are, tell what the errors are. Not too big pictures, please follow the EuroBricks guidelines. One set in one file. So not one set in 2 files, or 2 sets in file. The set should be build using the original instructions. Exporting models from ldd is forbidden unless you have the permission from the original author. Pleas do check everything very, very carful (also the inside of the model), because the export is not very accurate. Models like Montly Mini Builds or Club models are allowed. software files/programs that are allowed MLcad SR3D Builder Leocad Bricksmith BrickDraw 3D LDCad
Did you know that any standard EV3 brick is capable of controlling the LEDS separately? And that the display is capable of displaying 4 shades of gray? No, this extra functionality is not available via the standard programming environment that Lego provides. But if you use low level programming (I used EV3DEV in combination with C++), you have. See the example below. You can read my article at our blog here: https://siouxnetontrack.wordpress.com/2020/04/25/lego-mindstorms-ev3-with-an-image-with-4-different-shades-of-gray/ Or have a look at the Youtube videos. Enjoy. Hans
