hi
opened up an old wheel mouse. a wheel with perforations is revolving and a photo-transistor, led pair sense the gaps and closed portions of the wheels. how does it get to know in what direction the mouse is moving? i mean the direction of spinning of the wheel.
please anybody who knows tell me.
thanx.
