大家好,我是泰可之月的周扁,今天这节课上我们组装了一个基础的家庭电路,来介绍一下我们今天需要用到的器材。一个锂电池,家庭通用的 一个主板,相当于供电局一堆导线,一个 led 灯是二极管,灯泡跟那种普通的白痴灯不一样,一个电阻,一个开关, 这个锂电池通过导线接到主板上, 这里的电压三点三伏,这个 g n d, 它是负极的意思,接两根导线代表正极和负极, 正极一定要接正极,负极一定要接负极,正极只要接到这里,整一横横都是通电的,这边正负极标着正负极的,这边只有横横是通电的,其他这里竖竖列都是通电的。 保险将正极的标记接到这里,那么这一竖列的电都是通的了,接到了开关上,而开关又把电传到这里,再通过一根保线加到这里。后来我们发现 led 灯承受不了这么大的电压, 我们加装了一个电阻,竖列通电横头是不通电的,再通过这里, led 灯亮起来之后, 这个电路就会回到负极,再通过负极通道这里返回这个主板上。好了,谢谢大家。
