Roomba Part
What does LED / PT mean when defining electronics parts?
I know that LED means Light Emiting Diode but what is the PT?
these are used for TACH monitoring in a roomba.
Just wondering what PT stand for?
I know that the LED produces a signal on one side of a wheel and the PT senses the signal so as to monitor the speed of the robot. just dpnt know what PT stands for..
Light Emitting Diodes. It is a simple PN junction in a clear casing. It grows when current is passed though
