Gear tooth sensor not driving to ground
Hi. We hooked our gear tooth sensor to an USB oscilloscope and while its putting out a square wave, its not driving to ground. It ranges from 3.8 to 3.9 volts when plugged into digital input 1. And yes, digital i/o 1 is set as an input in code. If I unplug it from the robot controller. It puts ranges from ground to around 1.4 volts. Probably because it doesnt have 5V then.
Could the sensor be bad?
Brian
