When designing an opto-coupler circuit for a CNC machine, the micro-controller much be able to interface with the opto-coupler in the limit stop when the bed has reached its extreme x-axis limit. Which of the following is true for the sensor and the micro-controller interface? A. None of the above as the sensor does not work with micro-controllers.
B. The output of the photo-transistor in the opto-coupler circuk can be directly connected to the micro-controllers input pin
C. A opto-coupler drar needs a smoothing cult before it can be interfaced with a mer oder due to the fact that the oplo-coupler le analog controller reasonal
D. The microcontroller cant interface with the phototransistor opto-coupler eroult since i analog and the more controller is digital
