1, first read through the "plc system manual" (whether you can understand, first understand the approximate, in order to learn to find when programming); The utility model provides a disposable electronic cigarette, comprising: a hollow shell, the bottom of the shell is provided with a lower cover; the shell contains an atomizer, and the outer side of the atomizer is sheathed with a disposable cigarette A bomb, a microphone cover is arranged under the atomizer, a microphone is covered under the microphone cover, a battery is arranged on one side of the atomizer, and an upper cover is arranged on the top of the casing; The atomizer includes an atomizing core, an oil-absorbing cotton sleeved on the outside of the atomizing core, and an atomizer outer tube sleeved on the outside of the oil-absorbing cotton. The disposable electronic cigarette provided by the utility model absorbs the smoke oil on the surface through the absorbing cotton, and then atomizes the smoke through the atomizing core, which greatly reduces the risk of oil leakage, at the same time, reduces the burning of cotton and ensures the smoking taste.The utility model provides a disposable electronic cigarette, comprising: a hollow shell, the bottom of the shell is provided with a lower cover; the shell contains an atomizer, and the outer side of the atomizer is sheathed with a disposable cigarette A bomb, a microphone cover is arranged under the atomizer, a microphone is covered under the microphone cover, a battery is arranged on one side of the atomizer, and an upper cover is arranged on the top of the casing; The atomizer includes an atomizing core, an oil-absorbing cotton sleeved on the outside of the atomizing core, and an atomizer outer tube sleeved on the outside of the oil-absorbing cotton.

2. Start with the position control logic, gradually increase the timing, counting and other conditions, and rationalize the relationship between OR, AND, and NOT;
3, and then practice integer arithmetic, real arithmetic, type conversion;
4, range conversion, PID adjustment loop establishment and understanding of P, I, D parameters (preferably have a physical loop verification, such as inverter + motor + speed sensor);
5, loop, sequence, jump and other program control (try to avoid jumping, non-jumping is also the better the jump is better);
6, interrupt, communication, position control....
7. A further requirement is to carefully understand the working principle of the function block under the premise of using commands and function blocks to make your program run safer and more stable.
