The invention is an invention of a learning method, and realizes creative learning through development and integration of module integration, in addition to developing a main function control module and a controlled module, and also integrating a plug-and-play system with a module matching mechanism to provide wireless remote control function. And the interactive device structure of the connection module mechanism can be completed through voltage detection; in particular, when the module is connected in series, how to expand the diversity of the interactive module presentation in different situations through the matching mechanism, and provide two module matching groups The first is the basic preset active pairing master module and the controlled module, and the second is that the mobile phone interface is more flexible. The master control module and the controlled module do not need to be physically adjacent, thereby improving their cross-domain. Application of electronic motor creative teaching aids.

Common LEGO modules in the market (such as IEEE Transactions on,EDUCATION,VOL.54,NO.3, pp.452-461 and Parallax Inc., http://www.parallax.com/), motion control theory Such as 2010 IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS, VOL.57, NO.10, pp.3297-3307) or motor control teaching experimental version (such as 2012 IEEE TRANSACTIONS ON EDUCATION, VOL.55, NO.4, NOVEMBER, pp508- 516), the method is mostly to provide a complete set of hardware circuits with firmware, and with the necessary algorithms. The fixed experimental version of the scientific engineering education experimental platform is easily limited to a single platform that can only carry out teaching objectives and develop practical skills on specific topics. For example, LEGO's teaching platform is limited to a fixed hardware teaching platform, the firmware program can only adjust some parameters, students can learn skills on the platform is limited; some teaching platforms can be firmware update, but limited by hardware Circuits, the limited hardware project provided is limited. If such research is performed, the firmware adjustment will be difficult due to the unclear relationship between the register and the connection.

The technical method of LittleBits is to use the automatic detection to achieve the system when using the module block connection. Features. Through any combination of modules to attract readers to learn to enhance the teaching effect (http://littlebits.cc/ is the company's website, there is no in-depth discussion of journal articles). Its characteristic is that the circuit pin is used as a communication mechanism in a fixed form, but it does not discuss the complexity required for the hardware or firmware to detect the serial module. The related information does not discuss the inter-module negotiation method (autonegations). It is impossible to judge whether the module communication is achieved through flexible communication protocols and the transmission packet is reduced. It is worth mentioning that the mechanism does not discuss the module matching mechanism, and the output module is more fixed in one form and is less prone to generate more kinds. Combine to provide a context for creative thinking.

This creation uses innovative ideas to transform the creative combination of different input and output modules into a module pairing problem, so sound, light sensing, power supply, master and wireless network protocols, and other useful functions in the future are easily integrated into this work. . Compared with the current literature teaching tools or patents, this creation provides methods for learning general modules (master modules and controlled modules) and the realization of creative scenarios, as well as hot plugging and module expansion. The user creatively thinks about the required functions, and both the main control module and the controlled module include a microcontroller to achieve a higher flexibility and higher accuracy teaching application according to the user design program. And the interactive module is integrated into the teaching result, and because of the simple and easy to use mixed wireless communication form (mobile communication and wireless network), one or more sets of master modules and one or more are dynamically updated through the mobile phone interface. The controlled module is connected, the user command is transmitted to the first module of the serial configuration, and the information and commands are transmitted through the inter-module agreement to achieve all the module function settings, and the mobile phone interface setting is flexible to allow the main control module. It is adjacent to the controlled module without physical location. It can be used as a learning platform for high school students, junior college students and non-undergraduate students, achieving the goal of cross-disciplinary learning and creation.
