Supposedly you can program multitasking but I am finding it is not truely multitasking. ie; I have one thread reading the ir sensor in a loop and storing the value in a variable, then I have another thread which reads that variable and controls the motors. But I am finding that the first thread is not continually looping, it seems to wait for the other thread to finish before the loop re-enters. I have also tried using multiple start(s) and it seems to behave the same as described above. Does anyone know if I can write a real multitasking program using the ev3 programming tool?

Great work, I really like it.

Hi all, I'm new in town and thought the pub would be the best place to meet people. :-)

Nice creation, got me thinking about trying to make one too.

Great video, thanks for sharing.

Hi, I'm a new member from Ajax, Ontario. Merry Christmas everyone.

Thanks for the welcomes. dr_spock, where in Canada are you? I am in ajax ontario.

Very nice work efferman, I am new to this site and had no idea people were making custom parts for lego and selling them. Will take me a bit of time to get through this whole thread. Thanks for sharing.

Hi Ed, I am not retired yet and probably not for another 17 years, young kids finish university when I hit 72, hopefully I am allowed to work that long. I always loved robotics, and have really been thinking of arduino's etc, maybe cnc my mill or lathe in my shop, but really I don't have the time for that, the lego route should fit the bill for now to get me playing with things and my kids can also play along, both girls, one is actually in the robotics club in school and really likes legos. Programming specific forum(s) would be great. So, remember this is my third day playing with the ev3 and I wonder what benefits there are in having either a single start and a big loop or having multiple starts each with a loop. I can only put in image url's here so it's a pain to show quick pictures, hopefully people will understand what I mean. I am going to do some videos of programming this ev3 once I figure it all out, maybe help out some other people. I found a few colour sorters, did you have a specific one that I should look at?

Thanks for the replies, I am scouring the net for info, I just have not found any complicated programs to look over. I am a programmer for over 40 years so programming is not an issue, it's understanding how to make more complicated programs work in the graphical tool. I will look into the other programming interfaces mentioned. One question I do have, I have tried to write to a variable from 2 different parts of a program, when I try this it does not work and the whole program seems to not do what it is supposed to. Any ideas?

Just got an ev3 and am having a hard time figuring out a few things with the ev3 graphical programming interface. I don't want to bore you with a bunch of questions. Is there some in depth articles or videos around that get into more complex programming using this gui? I just need to know what I can and cannot do, what is good way to structure a program to be able to control motors based on multiple variable inputs from sensors. I've only been at this for 2 days so forgive me if I am asking stupid, nonsensical or obvious questions.

Finally got mindstorms ev3. Joined the site as it seems to be the best lego forum site around. Merry Christmas everyone. Steve
