There have been many things these days, and I have not updated my blog. In fact, I haven't compiled any programs recently. I made a circuit or a Analog Circuit for the lights at home during the Spring Festival, there is no such classification here. Put it under C ++. Although this circuit is relatively simple, I have observed that there seems to be no similar circuit on the Internet. This is an optical control switch. The circuit diagram is as follows

feedback operation.The printer, when the paper is rolled out, hinders the on-beam printer of the photoelectric switch from knowing to the first few sheets of paper, or stops printing.In the purchase of the photoelectric switch with a universal table for detection, you can find the reaction between the receiver and the voltage relationship.The indicator light for

Cisco switch status lights are all available on the front panel of the Cisco switch and are used to monitor system activity and performance.

These LEDs are called LEDs ). The indicators on the front panel include: · System indicator lights · Remote powe

Last night, I started to read the beauty of programming. I just saw an interview question in the preface. It is said that most of the early candidates for the PM position encountered this question: There are three lights in the room, and three switches outside the room control the three lights respectively. Only when you enter the room can you see which one is on. Excuse me, how can I enter the room only once and specify which switch controls which

How to switch out the speed of light input method, this situation is usually in their own computer equipped with more than two input methods. We can generally use the "ctrl+shift" key to switch, has been pressed to appear the speed of light input method. or directly through the Language bar to choose the speed of

Each time the number of lights is, toggle the light switch, (may be turned on or off).idea: The first thought is the simulation, but timed out, and later found that the state of N is determined by the approximate number of N, when about a number of even is, the state of N is unchanged (closed), when an odd number of times the change (open).
