Re: Help with the Kit Gear Tooth sensors

Use a multimeter to test the sensor, I believe it shorts signal to ground when a tooth is detected, so an open connection (bad connection or loose wire?) behaves the same as no tooth detected (The RC has pullups, so with no connection, it defaults to 1). See if you can see a voltage change on the signal pin to around 0 volts when there's a tooth present. If that works then perhaps you aren't making the right connection to the RC, or you have the digital I/O in question set as an output. Start small, work from there, it's probably more likely a silly mistake than a damaged sensor. And silly mistakes are fun to laugh at later, so that's no big deal
