![]() ![]() ![]() drag and drop, cloud-based platform for programming LEGO EV3 and NXT robots. But this appears to require programming at the internal serial port level which is probably beyond the fifth graders I am coaching. For more information, see: Introducing EV3 Basic. I will try to get the sensor working via the link you gave. Lego has a close to great product but so many details are maddening. Founded in 2014, EV3Lessons has grown to become the premier site for learning to program the EV3. The tutorials are clear, to-the-point, and comprehensive, with something for every level of user. Sorry, my rant isn’t directed at you you’ve been very helpful. EV3Lessons provides a complete set of LEGO MINDSTORMS programming lessons for teams, teachers, and robotics enthusiasts. (the robot is moving on a straight part) AND (the color sensor finds a gap in the track) Depending on your existing solution you might need to code dedicated methods to identify the two sub-cases and then call them repeatedly to. (no G, and it works fine with my version 2.0). As you already have a working program for the continuous line, you just need to add provisions for the cases when. Perhaps I should have known 8547 was codeword for “Retail version, temperature sensor won’t work!” Yes the temp sensor order page mentioned “LME NXT Software 2.0 or higher is required! ” (note no G) but then the color sensor order page says “Requires LEGO® MINDSTORMS® Education NXT Software 2.1. In my defense, Lego itself doesn’t consistently call the development software NXT-G (no G anywhere on that download site, the file name, nor in the software’s About file…) And I don’t see any explanation of retail vs educational versions of the software on the Lego sites or download pages.
