It is the appropriate quantity of green laser pointer

Laser radar detection altitude of 1500 meters from the ground, the beam diameter of only 10 cm, can be drawn to distinguish changes in the level terrain, which is microwave radar can not. Second, the laser radar is much lighter than microwave radar. In order to maintain a certain distance from the same beam size, laser radar with a diameter of only a few centimeters of lens, and use of microwave radar antenna diameter of 60 meters.You may use the cell phone jammer directly without installing software. Remote microwave radar antenna, a larger diameter, generally installed in the radar station in the fixed. The entire laser radar can be shipped by truck, and even a few people can carried away. Again, the laser radar can measure the speed of the target parameter, which is the normal radar can not do. Laser radar as well as good resistance to interference, radio interference from the ground, which is highly regarded as a military characteristics.More actions of green laser pointer  have been taken in the workshop
Rich C language data types, data types: integer, real, character, array type, pointer type, structure type, union type, etc.. Can be used to achieve a variety of complex data structures of computing. And introduces the concept of pointers to make the program more efficient. Addition, the C language has a powerful graphics capabilities, support for multiple monitors and drives, and calculation functions, powerful logical judgment. C is a structured language structured language distinguishing feature is the separation of code and data, that is, the various parts of the program in addition to the necessary exchange of information independent of each other. Clear, structured way to enable the program level and ease of use, maintenance, and debugging.

Debug (1) 40-6 line priority encoder, the absence of detailed reading of the priority encoder truth table, I consider a priority encoder for low priority coding standards (designed to take trumpet) does not meet the standard. But after an error is found, the hardware circuit without modification, as long as the modified coding standards for the collection of large, we can solve the problem. By amplification of the response signal of the photocell, coding, microcontroller port P1 is reached, a certain delay, the SCM accurate and effective data collection through an external interrupt, you should know the approximate range of the delay. The preparation of the SCM process, write a subroutine in a delay of 2ms, and can call for a certain delay.
