Description

Resistance teach pendant

technical field

The utility model belongs to a teaching instrument, in particular to a resistance teaching instrument for reading resistance color rings

assisted teaching demonstration.

Background technique

In electronic technology courses, when it comes to the identification of resistance color rings, the teacher usually tells the basic naming rules first, and students memorize the corresponding numbers of colors according to the theoretical content. When strengthening and consolidating, the teacher draws the resistance on the blackboard and then marks the color, and the students read it. In this case, the teaching effect cannot be achieved due to the lack of actual colors; or the teacher uses the resistance of the object to let the students read according to the number. The former has slow readings, low efficiency and lack of image; the latter is not convenient for students to observe, and often because the individual resistance is very small, it can only be seen by students in a small range, so the teaching effect and teaching efficiency are often not high.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a resistance teaching instrument, which converts the abstract teaching problems in the actual teaching into practical operations, satisfies the curiosity of students in learning electronic devices, and also accelerates students' understanding of the resistance color ring. study.

The utility model is realized by the following technical scheme: a resistance teaching instrument, including a microcontroller for data processing and calculation, connected with the microcontroller for inputting parameters or color button module, and the microcontroller Connect the display for displaying the color ring color and resistance value of the resistance, and the power supply module for supplying power to the above-mentioned modules; install the above-mentioned devices in a casing.

The beneficial effects of the utility model are: transforming traditional abstract electronic teaching problems into practical operations, which is simple and convenient, reduces the burden on teachers, accelerates students' learning of resistance color rings, improves teaching efficiency, and has certain practical significance.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a block diagram of the utility model;

Fig. 2 is a structural schematic diagram of the utility model.

Detailed ways

As shown in Figure 1, a resistance teaching instrument has a microcontroller for data processing and calculation, a key module connected with the microcontroller for inputting parameters or colors, and connected with the microcontroller for displaying the color of the resistance A display of ring color and resistance value, a power supply module for supplying power to the above-mentioned modules; the above-mentioned devices are installed in a casing.

In this embodiment, the display is a liquid crystal display. The button module includes a color input button and a number input button, and realizes an input color calculation resistance value mode and an input resistance value calculation color mode. Input color to calculate resistance mode: the teacher selects various colors on the teaching device, determines a resistance, and asks the students to try to read the number, and then the teacher presses the view button to determine the actual resistance value. Enter the color estimation mode of the resistance value, let the students infer the color according to the reading, and then the teacher presses the OK button to display the correct color.

As shown in Figure 2, the various parts in Figure 1 are installed in the housing, where the keys and display are installed on the surface of the housing, and the power module and microcontroller are installed inside the housing.
