Troubleshooting Exercise 5A - Motor Basics

Hello,

I'm having some issues with my exercise 5A where the motor doesn't move at all regardless of the switch position. I read a couple of other peoples blogs about this and they seem to have had issues to, but never shared a solution. One other student noted that our switch has 3 setttings instead of 2 like in the book, so perhaps that could be the problem? Does anybody have any advice as for how to move forward with this circuit?

Thanks,

Silas

  • 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.

  • 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.

  • 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.
