Electronic body reaction tachymeter educational aid for children

Abstract

The invention discloses an electronic body reaction tachymeter educational aid for children. The educational aid is characterized in that a linear light-emitting array composed of eight light-emittingdiodes-white light is arranged on the front side of a PCB, nine straight-plug resistors and one switch diode are arranged on the front side of the PCB, three tile capacitors are arranged in the neighborhood of the switch diode. A nor gate chip is arranged in the neighborhood of the left side of the tile capacitors. A buzzer is arranged in the neighborhood of the right side of the tile capacitors.A light-emitting diode-green light and a register are arranged in the neighborhood of the right side of the buzzer. Two electrolytic capacitors are arranged at the upper right corner of the front side of the PCB. Two digital logic circuit chips are arranged on the front side of the PCB and located on the two sides of the straight-plug resistors respectively. The educational aid has the advantagesof being novel in principle, easy to detach, convenient to adjust and capable of teaching children through lively activities, having wide commercial prospects and being capable of filling up the related technological blank and also capable of generating large social benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of electronic teaching aids, in particular to an electronic human body reaction velocimeter for children's educational teaching aids. Background technique [0002] Relying on a variety of electronic teaching aids, taking creative hands and creating brainstorming as the educational purpose, introducing the educational concept of innovation in thinking and creation in action to cultivate and develop children's abilities, and adopt the teaching mode of "learning by playing". This is different from the evaluation method of quantifying children with scores in traditional teaching. [0003] At present, educational electronic teaching aids have single functions, fewer types, high packaging level, and the electronic devices are soldered on the circuit board, so students cannot manually plug and debug. However, there are few highly flexible and pluggable modular electronic teaching aids at present. . [0004] In order to sol...

AI Technical Summary

Problems solved by technology

[0003] At present, educational electronic teaching aids have single functions, fewer types, high packaging level, and the electronic devices are soldered on the circuit board, so students cannot manually plug and debug. However, there are few highly flexible and pluggable modular electronic teaching aids at present.

[0004] In order to solve technical bottlenecks such as relatively backward design level, difficult debugging, poor training effect, and difficult repeated disassembly of electronic components in the current prior art, the present invention discloses an electronic human body reaction tachometer children's educational teaching aid, which has a low cost, Novel scheme, novel principle, high flexibility, short debugging time, and the ability to reassemble electronic devices on site, meet the actual needs of children's educational training, fill the gaps in related technologies, and generate greater social and economic benefits
