Then apply direct voltage to this input to the tube drive circuit for led display, in rotation direction detector to. From the experiments, we can see that the system proposed has to work according to the principles as well.
Then the DC voltage input to the LED driver circuit to detect the direction in which the display rotates. The study reveals that the proposed system is working according to the principle as well.
The light pressure here to enter drive circuit of LED lamps to display detection in the direction turning. From the experiment, the proposed system is working principles as well.
