simpleProgramDesign, and then start coding. Many of the codes are direct operations on database tables. The business description is usually as follows: press a button to open a screen, query a data from a data table and display it on the interface. Press a menu to modify a field in the data table ...... This is the direct operation from the UI to the dB, and there is no abstract level. Such a design has limited adaptability to changes in requirements. Demand changes often occur during softwar

Arduino Introduction: Arduino is a convenient and flexible, easy-to-start open source electronic prototyping platform. Includes hardware (various models of Arduino board) and software (Arduino IDE). Developed by a European development team in the winter of 2005.　　Its members include Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, David Mellis, and Nicholas Zambetti. It is built on the open source simple I/O interface version and has a processing/wiring development environment that

First, the general introduction:Stepping motor is an open-loop control element stepping electric part which transforms electric pulse signal into angular displacement or line displacement. In the case of non-overloading, the speed of the motor, the position of the stop only depends on the frequency of the pulse signal and the number of pulses, and is not affected by the load changes, when the stepper driver receives a pulse signal, it will drive the stepper motor in the direction set to rotate a

-way motor-made 4-way trolleyPin is really not enough, the extended version can only support 2-way motor drive or 1 stepper motors, so to remote control 4 drive intelligent parallel, the left wheel connected all the way, the right side of the road, such a benefit is turning when the turn, side reversal, without differential speed, direct 360 degrees in situ rotation. Cool.(v) PostScriptAlways say these things do not have technical content, each sensor

power, the lower the voltage level, you can use the higher the PWM frequency. Because low-voltage MOSFET switching frequency can be very high, and high-voltage IGBT is difficult to quickly switch. Normal motors, 10K to 20K, no problem. We do kw class main inverter, switching frequency 10K./*PWM Speed Control program of ======= DC motor ========*/ /*Wei Dong Studio robots51.51.net June 2006*/ /*The crystal oscillator is 11.0592M and the PWM frequenc

KISS, DRY, MVC, OOP, REST(1) Kiss refers to keep It simple,stupid (from Wikipedia), referring to the principle of simplicity in design to avoid unnecessary complications.(2) dry refers to don ' t Repeat yourself (from Wikipedia), specifically to avoid duplication of code in programming and calculations, because it reduces flexibility, simplicity, and can lead to inconsistencies between the code.(3) OOP is object-oriented programming, which refers to object-oriented programming.

General Motors has used its credit card, the GM card, and has 12 million customers with credit cards in its database. Through observation, the company can learn what kind of cars they are driving, what kind of cars they plan to buy next, and what kind of vehicles they like. For example, if a customer with a credit card expresses interest in a truck, the company ca

trip outside China.This Riben company, after all, has pulled me from the poverty line to a well-off level, so that I can occasionally visit the department store Meimei,Although only occasionally. After hard work last month, I finally jumped to the ideal European company (not a European or American company, but an American company ).In fact, the company is not very good. Two of my friends who work overtime at most are American companies, one is General Motor
