Abstract

红绿灯涉及一种教具。红绿灯的电路是NE555模块与CD4017模块、数码管、计数器相连接,最后与红色灯与绿色灯相连接。教学时,只需接通电源,NE555产生计时信号,送至CD4017和数码管完成倒计时任务,并将信号送给计数器,最后控制红绿灯的亮、灭。采用红绿灯的有益效果是能增强教学的形象性、直观性,激发起学生对城市交通规则的兴趣与思考,对学生掌握红灯停、绿灯行的要求有了深刻的印象,加深了理解,取得很好的教育效果。

Description

红绿灯
技术领域:
本实用新型涉及一种教具。
背景技术:
在小学教学中,农村的学生很少进入城市,对城市内的交通信号很少了解,则对交通规则中的红绿灯方面的知识接触更少。
发明内容:
本实用新型的目的是要提供一种红绿灯教具,红绿灯的电路由NE555模块、CD4017模块和数码管、计数器连接而成,最后与红色灯与绿色灯相连接。教学时,只需接通电源,NE555产生计时信号,送至CD4017和数码管完成倒计时任务,并将信号送给计数器,最后控制红绿灯的亮、灭。红绿灯教具能增强教学的形象性、直观性,激发起学生对城市交通规则的兴趣与思考,对学生掌握红灯停、绿灯行的要求有了深刻的印象,加深了理解,取得很好的教育效果。
红绿灯的电路是使NE555模块与CD4017模块、数码管、计数器相连接,最后与红色灯与绿色灯相连接。教学时,只需接通电源,NE555产生计时信号,送至CD4017和数码管完成倒计时任务,并将信号送给计数器,最后控制红绿灯的亮、灭。
采用红绿灯的有益效果是能增强教学的形象性、直观性,激发起学生对城市交通规则的兴趣与思考,对学生掌握红灯停、绿灯行的要求有了深刻的印象,加深了理解,取得很好的教育效果。
附图说明:
图1是红绿灯的电路示意图。
具体实施方式:
红绿灯的电路是使NE555模块与CD4017模块、数码管1、计数器2相连接,最后与红色灯3与绿色灯4相连接。教学时,只需接通电源,NE555产生计时信号,送至CD4017和数码管1完成倒计时任务,并将信号送给计数器2,最后控制红绿灯3、4的亮、灭。

Claims (1)
