Re: Help with Gear Tooth Sensor
The gear tooth sensor provides a short high-going pulse every time a metal gear tooth passes the face of the sensor. It requires 12 volt power, and is intended to be connected to one of the interrupt-capable digital inputs on the Robot Controller.
Software on the RC is used to count the pulses from the sensor. (I believe there's a hardware counter as well, but I've never used it.)
You can view its output directly with an oscilloscope.
