"There Will Come Soft Rains" is a short story by science fiction author Ray Bradbury, first published in 1950. It tells the tale of a futuristic, automated house that continues to function long after its human occupants have been destroyed in a nuclear war. The story is notable for its use of personification, as the house and its various systems are described as if they were sentient beings.

One of the most famous quotes from the story is the opening line: "The morning of August 4, 2026, was clear and sunny, with the fresh warmth of a full-summer day." This sets the stage for the events that unfold, as the house goes about its daily routine, unaware that its inhabitants are no longer alive.

Another memorable quote from the story is: "The house stood alone in a city of rubble and ashes. This was the one house left standing." This passage highlights the devastation that has occurred as a result of the nuclear war, and the contrast between the house's pristine condition and the ruined city around it.

A third quote that is particularly notable is: "The trees were green. The grass was green. The streets were quiet." This passage serves to further contrast the house's normal functioning with the chaos and destruction that have taken place outside its walls. The trees and grass continue to grow, while the streets are silent, suggesting that there is no longer any human activity in the area.

In conclusion, "There Will Come Soft Rains" is a thought-provoking short story that uses personification and vivid imagery to explore themes of technology, survival, and the dangers of nuclear war. Its memorable quotes serve to enhance the story's themes and add to its overall impact on the reader.

The Advantages & Disadvantages of Microcontrollers & PLCs

programmable logic controller advantages and disadvantages

A second advantage is that the programming language that the controller uses is very easy. The advantage of PLD is re-programmability, they have replaced special-purpose different types of logic devices like logic gates, flip flop, counter, and multiplexer in many semi-custom applications. And it had to be modular so that components could be changed and added. These controllers are designed to be used in an industrial environment, so they will not easily be damaged by vibrations pressure from the machinery. For communication, you can use various standard. You can simply connect to the PLC and make changes within the program. It occurs smaller in size, especially compact PLC.

Let us see below how a PLC works. As a result, PLCs can quickly become overloaded, and determining which signal might be causing an issue can be challenging. What are the disadvantages of PLC over relays? Disadvantages of using a signal chain include the fact that they can be more expensive than PLCs. It's simple enough so that even a worker who doesn't have a strong background in programming is able to input commands successfully, but complex enough to do almost anything a company needs. Separate timers, counters, and cube relays are no longer needed. It is fast and can easily give respond to the process very quickly. Like any other component, they also have some drawbacks and reasons why they may not be used in certain applications.

It works on a fully automatic system from start to finish. Some applications that perform a single function, is not efficient in the use of PLC. Training is about the same too. Programmable relays also include function keys and buttons to navigate, enter and edit the program, and start and stop the configuration. Answer: PLC or Programmable Logic Controller is a machine that focuses on automating different electro-mechanical processes applied in various industries, plants, and other automated industries. The ability to also back up machine programs makes them easy to replace and diagnose issues.

And they are not difficult to program either. Programmable relays can be modified faster and easier than their PLC counterparts because they typically function as relays and timers only. That time there are little chances to happen in any kind of accident. One or two skilled workers can then fill in for the unskilled labor by programming the controllers to run the machines. They are now typically more reliable than standard relays and can perform millions of cycles.

It has different operating modes and consists of microprocessors, a control unit, and a logical unit, and also communicates with the other module. This individual processing also makes diagnosing issues easier because problems can be traced to the exact signal. One of the main expenses for a company is having to pay workers to perform the tedious activity of controlling machinery. They are now encroaching upon PLC territory. As programmable relays improve and add more intelligent controls, they will continue to replace PLCs in more areas.

When using a PLC they only require a couple of connections to provide the unit with power. Using programmable relays controls OEM costs and minimizes inventory levels and purchasing overhead. Their programming language is effortlessly seen, so they can be modified absent a lot of trouble. These cards can rapidly be included or expelled from their space in the transporter. In addition, PLCs are usually easier to program than signal chains.
