It was a recommended book that the Lord had transmigrated into his world.

The following are some of the main points of the 5V relay circuit controlled by the single-chip computer: ** 1. In terms of hardware connection ** 1. ** Connection between the pins of the single-chip computer and the relay ** - The output pin of the microchip needed to be connected to the control end of the relay. For example, in a common 51-bit single-chip computer, if the STC89C52 single-chip computer is used, one of its output pins (such as a pin of the P1 port) can be connected to the control input pin of the relay module. Relays generally have two ends of the coil, one end connected to the output pin of the microchip, and the other end connected to the ground or power supply (according to the circuit design of the relay module). 2. ** Power supply ** - The 5V relay required a 5V power supply. You can use the same 5V power supply as the single-chip computer, but pay attention to whether the power of the power supply can meet the needs of both. If the power supply is insufficient, it may cause the relay to not work properly or the single-chip processor to operate unstably. - In order to prevent the relay from interfering with the power supply of the single-chip computer, it may be necessary to consider power isolation. For example, the use of optical isolation or relay driver chips could isolate the power supply of the single-chip processor and the relay to ensure the stability and reliability of the signal transmission. 3. ** Protective Circuit ** - In order to prevent current surges, a suitable current limiting resistance or induction could be added to the control end of the relay. Because the relay may produce a large current impact at the moment of switching, this may affect other components such as the power supply and the single-chip computer. By adding these components, the current can be smoothly controlled. - In order to reduce the electromagnetic interference generated by the relay at the moment of switching on and off, a suitable filter circuit could be added to the control end and power supply end of the relay to limit the transmission of electromagnetic noise. ** 2. Program Control ** 1. ** Initialize ** - In the program of the single-chip computer, the port connected to the control pin of the relay must first be initialized. If you use the C language programming of the 51 single-chip computer, you may need to set the corresponding register to set the control pin to the output mode. For example, when using a pin of the P1 port, the relevant register of the P1 port must be set. 2. ** Control logic ** - When the relay needs to be controlled, the high and low levels are output to the control pin through the single-chip computer program. For example, the output of a high level causes the relay to be pulled in (if the relay is triggered by a high level), and the output of a low level causes the relay to be disconnected. The specific logic needed to be written according to the type of relay (such as high level trigger or low level trigger) and the actual control requirements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The selection of agitators required comprehensive consideration of various factors. If you choose a reactor in Shandong, you can generally start from the following aspects: 1. ** The properties of the raw materials **: Investigate the stickiness, density, and other properties of the raw materials, and then choose the stirring equipment suitable for the properties of the raw materials. 2. ** Technology requirements **: Clearly define the production process requirements, such as the requirements for assimilation, mixing, and dissolving, and then choose the equipment that can meet the production process. 3. ** Past experience and reference **: - If there is a similar application and the mixing effect is satisfactory, you can choose the same whisk. - If the production process has strict requirements for agitation and there is no similar type of agitators for reference, it is necessary to make a comprehensive evaluation of the process, equipment, agitation requirements, economy, etc. to find out the main control factors of the operation, so as to select the appropriate type of agitators. - For large-scale or newly developed agitation equipment, it is necessary to conduct certain experimental research to find the best type, size, and operating conditions of the agitation device. After the pilot test, it can be applied to industrial devices. 4. ** According to the situation in the kettle **: According to the physical properties, capacity, and stirring purpose of different media in the kettle, the corresponding agitators are selected to promote the chemical reaction speed and improve production efficiency. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

To improve children's painting skills and aesthetic ability. #(2) Teaching content 1. The shape and color of the raindrops. 2. Watercolor painting techniques and tools. 3. The conception and realization of creative paintings. #(3) Teaching process 1. ** Introduction Stage ** - The teacher showed the shape and color of the raindrops through the PowerPoint presentation, and used vivid language to stimulate the curiosity and creative desire of the children. For example,"Children, look at these bead-like things on the screen. What are they? Yes, raindrops. Raindrops come in different sizes and colors." 2. ** Learn watercolor painting tools and techniques ** - The teacher took out the watercolor painting tools and used simple and easy-to-understand illustrations and slow and clear physical demonstration to explain the watercolor painting tools (such as brushes, paint, etc.) and the basic painting methods (such as dipping the paint, how to control the amount of water, etc.) to the children. The teacher could demonstrate and say,"Look, this brush is like a small magic wand. Let's dip it in a little paint and then gently draw on the paper. You can draw beautiful colors." 3. ** Conception of painting content ** - The teacher showed a painting of Colored Raindrops and guided the children to observe the color, size, and arrangement of the raindrops in the picture. Then, the children could imagine their own works. They could ask the children,"Children, what color do you want the raindrops to be? Is it as colorful as a rainbow or as blue as the sky?" 4. ** Painting Practice ** - The children would practice painting using watercolor painting tools and techniques according to their own ideas. The teacher guided the child in the process of painting, reminding the child to pay attention to the safety of the brush and encouraging the child to create boldly, such as saying: "Baby, the color of the raindrops you drew is so special." 5. ** Exhibition and evaluation of works ** - The children showed their completed works, and the teacher first gave positive affirmation and encouragement, such as: "Every child's raindrops are as beautiful as little magic." Then, he guided the other children to appreciate it together and give comments and suggestions, such as: "Look at this painting, the colors of the raindrops are so beautiful. Then, let's think about it again. Wouldn't it be more interesting if the raindrops were bigger?" #(IV) Reflection on Teaching 1. ** Strengths ** - In the teaching of watercolor painting, through detailed physical demonstration and illustration of watercolor painting tools and painting methods, children can better understand and master the basic watercolor painting skills. In the practice of painting, most children can smoothly use the tools to create. - In terms of content teaching, children were allowed to conceive their own works, which well cultivated children's creativity and artistic imagination. Many children could express the shape and color of raindrops according to their own understanding, and their works were full of childlike interest. 2. ** Inadequacies and improvements ** - When some children used watercolor paint, they did not control the amount of water well, causing the picture to be too wet or the paint to be too dry. He could add a small segment in the next lesson, specifically for the children to practice drawing on paper with different amounts of paint and feel the effect. - In the evaluation segment, the interaction between the children could be more sufficient. In the future, he could guide the children to ask each other more questions and learn from each other to improve the effect of the evaluation segment, so that the children could better get inspiration from each other's works. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
