Detailed Product Description: | Jiangmen learning machine to join, select the school and the first national brand to buy a "learning and the first" National Machine beneficiary families, they say: Shenzhen Small-kun (7 year old boy) mother: Great! To read through Sinology become very, very loose, I had spent a lot of money to buy a lot of sets of discs, there are no set is complete, wear flowers, lost, and stuck out of play. This Sinology machine, and everything the whole, I finally freed from the CD inside it. Fujian vast (three year old boy) father: the child's mother is doing Early Learning Center, we have been the classic sense, although the child hears finished "Rules", "Three Character Classic", but the machine still surprise us Sinology content too rich! Listen now round the child, nor even watched television. Now, I have to not go to school and the first Sinology machine Fujian agent, goods sent back, ten days for the sale of more than one hundred units, have never done such a good promotion products. Xiangtan - Zheng: I every day in the classroom, playing 20 minutes at noon Classic, a semester later, our class children, in memory, reading and writing have improved to varying degrees, the area where the speech contest, a prize, second prize are the kids in our class. This is a pleasant surprise, we did not think Sinology machine class kids more standard pronunciation, speech more appealing up! Learning and First Technology Co., Ltd. mainly produces electronic products, audio materials, communications equipment, and other educational products. Domestic and international sales. Over the years our products with its powerful, reliable quality, stable performance is known, the majority of users and dealers who praise. School and the first technology to provide customers with reliable products and fast scientific quality service. Let early education, Chinese culture and other fields of science and technology possible. The following article for information purposes only and K resistor each one, uF capacitor one, V power supply. Circuit works The final output of the circuit P port that is connected to the MCU external interrupt. When the phototransistor black line is not detected, it will output a low signal, then the output of the entire circuit is low. When the phototransistor detects the black line after the output level signal, then the signal is amplified through two, and then amplifies the signal to the microcontroller. When the rising edge of the pulse signal microcontroller feel when an interrupt is generated, so that the microcontroller to execute the interrupt routine, and ultimately enable the car to complete the response action. Figure signal detection circuit Fourth, the system formed by the total circuit diagram for the system to form a total of voice repeater chip voice recording technology in the application of the overall system circuit diagram voice repeater chip voice recording technology in the application software design based on Chapter III task program choices, and then the program carried out in the various sub-unit design, parameter calculation and component selection, and finally the individual points are connected together, draw a line with the design requirements of the complete system schematic. A clear system design tasks require the system design task specific analysis to fully understand the system performance, targets, content and requirements in order to clear the system should accomplish. Second, the program select the job requirements of this step is to put the system to complete the task assigned to several units of the circuit, and draw a function of each unit can represent the whole block diagram voice repeater chip voice recording technology in the Application Selector The important task is based on knowledge and information for the system's mission, requirements and conditions to complete the function of the system design. This process should have the courage to explore, to be creative, and strive to achieve design is reasonable, reliable, economical, full-featured and advanced technology. And the program should continue to carry out feasibility and flawed analysis, the final design of a complete diagram. Diagram must accurately reflect the tasks to be completed and each component of the function of the system's basic Jiangmen clear that learning machine to join, select the school and the first national brand |
