  • It took me a while to figure out about this exercise too. Make sure your robot is connected to the system. You need to open serial port by clicking on tools from the top-bar. Then write the command like
    f 50
    then press Ctrl+Enter to execute. 

    I hope this helps.

  • I had an issue where I did not read the instructions properly for this excersise where you need to open the Serial monitor (Tools, Serial Monitor) Ctrl_Shift+ M and you need to enter the speed value for the motors.   That along with the switch on will move the motors.  Just double check that.  I wasted a couple of hours on that silly mistake and even bought new motor boards thinking it was faulty.  Hope that solves your issues.

  • The only advice I can offer at the moment would be to check all the wires thoroughtly. Most important is that the perfboard doesn't always make a connection even though it looks like it should (i.e. wire seems firmly seated in hole).

    Often if I've tried several things with no joy I on a simple circuit I will just pull it apart and start again from scratch. I don't know why, but that often helps.

    Sorry I can't offer much more on this one.

  • HI :-) It sounds like you're posting them to the GROUP... rather than to your PROFILE. You should be posting them to your PROFILE, and then using tags to tag yourself to the groups. This got me, too... when I'd first started.

    For example: when you create a Wiki to handle your notebook, and add "pages" to it (containing your reflections), there is a dropdown under each page that allows you to post to your own profile. See my screenshot for an example :
