Hi folks. Just got an mBot for my daughter, and their website was down for awhile, so I couldn't download the stock software. I searched around and ran into the nodebot mBot repo. I got it basically working via bluetooth, and am trying to get the proximity and ultrasonic sensors working. The examples in the repo assume the prox sensor is plugged into port 2 and the ultrasonic sensor is plugged into port 3, but in the standard build the two are reversed. Obviously I could just switch them :), but wanted to keep it compatible with their software. I don't know that much about Arduino, and couldn't immediately figure out how to modify the examples to use the right pins - I tried just changing the sonar.js example to use "A3" (which appears to be the analogous pin on port 3 to pin 10 on port 2, if I'm understanding the labelling), but that didn't seem to work, presumably because it's a different type of pin?
