This general subject has been discussed here before. I'm sure you can search the lugnet archives for more info. However, as my supply of motors has aged, I too have noted that they do tend to seize or at least stiffen up with lack of use. I have (...) (24 years ago, 21-Jan-02, to lugnet.robotics)

I don't have any connector in the J11 space (middle right edge of the expansion board). All I have are 9 holes in the board that are in the same configuration as the bottom of the sonar module's 9-pin male connector. So if I solder the bottom of the (...)
