Abstract
The utility model relates to the teaching instrument field, particularly to a resistor demonstration instrument, comprising a microcontroller, a button module and a display which are respectively connected with the microcontroller, and a power supply module which provides power for all the modules mentioned above. The resistor demonstration instrument turns the traditional abstract electronic teaching problems into practical operation. The resistor demonstration instrument of the utility model features simplicity and convenience, reduces the burden for teachers, facilitates resistor chromatic circle learning for students, raises the teaching efficiency, and has great practical significance.
Description
Technical field
The utility model belongs to a kind of instruments used for education, specifically is a kind of resistance Teaching instrument, is used for resistance colour circle reading
Aided education demonstration.
Background technology
In the electronic technology course, when telling about the identification of resistance colour circle, generally be that the teacher tells about basic naming rule earlier, the student representes corresponding numeral according to the theoretical content color memory.When strengthen consolidating the teacher on blackboard, to draw resistance color-coded then, student's reading is in this case often because the kind of actual color can't reach teaching efficiency inadequately; Perhaps the teacher utilizes resistance in kind, lets the student according to digital reading.The former reading is slow, and efficient is low and vivid inadequately; The latter is not easy to observation of students, and often because the individuality of resistance is very little, only the classmate among a small circle can see that teaching efficiency and efficiency of teaching are often not high.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of resistance Teaching instrument, and abstract problems in teaching is converted into actual operation in the field research, satisfies the curiosity that the student learns electron device, also accelerates the study of student to the resistance colour circle simultaneously.
The utility model is realized with following technical scheme: a kind of resistance Teaching instrument; Comprise that one is used for the microcontroller of data processing and computing; Be connected the key-press module that is used for input parameter or color with microcontroller; Be connected with microcontroller and be used to show the colour circle color of resistance and the display of resistance value, give the power module of above-mentioned each module for power supply; Said apparatus is installed in the housing.
The beneficial effect of the utility model is: traditional abstract electronic instruction problem is converted into actual operation, and simple and convenient, alleviate teacher's burden, accelerate the study of student to the resistance colour circle, improve the efficiency of teaching advantage, have certain practice significance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model theory diagram;
Fig. 2 is the utility model structural representation.
Embodiment
As shown in Figure 1; A kind of resistance Teaching instrument have one be used for data processing and computing microcontroller; Be connected the key-press module that is used for input parameter or color with microcontroller; Be connected with microcontroller and be used to show the colour circle color of resistance and the display of resistance value, give the power module of above-mentioned each module for power supply; Said apparatus is installed in the housing.
In the present embodiment, display adopts LCD.Key-press module comprises color input button and numeral input button, and realization input color calculation resistance pattern is calculated color mode with the input resistance.Input color calculation resistance pattern: the teacher selects shades of colour on Teaching instrument, confirm a resistance, lets the student attempt reading numeral, and teacher presses and checks button then, just can confirm actual resistance value.The input resistance is calculated color mode, lets the student infer color according to reading, and the teacher presses definite key then, shows correct color.
As shown in Figure 2, the installation of the each several part among Fig. 1 is taken notice of in the housing that wherein button and display are installed in the surface of housing, power module and microcontroller are installed in the inside of housing.
Claims (3)
