    Hey folks,

    I have a basic question. I have set up one of my robots (3 wheel) to respond to commands from a wireless playstation controller and it works well.

    However, my program is written so that some button combinations result in one of the DC motors going 100% speed forward to 100% speed backward which results in an unpleasant *clunk* sound.

    My question: Is a sudden change from going 100% forward to 100% backward in a DC motor bad for it? Will I ruin the motors doing this?

    Not only do the motors get hot, but you end up drawing considerable excess current from the battery.
