  • Hi, I have questions about the IO pins;

    I used the io pins definition from the sample code, and tried to power the left motor with the following codes: digitalWrite(lmdirpin,1); // drive left motor forward digitalWrite(lmpwmpin,1); // left motor at 100%

    however, what I found is that I actually got potential difference on the right motor output channels

    similarly, when I tried to power the right motor, I got potential difference on left motor output

No public wish lists :(
