小风扇 两者许多相似的特性,都可以测试继电器可用性,但以上都有·极性·区分。 一定要插到位,其次旋紧螺丝要旋的足够紧!!! 确保足够的电压,5v口允许的话,用5v; 如果仅有3.3v口可用作电源正极,那么请让继电器独占这个口(最好直接插在开发板上的口上,而不要通过面包板间接来链接,减少和其他模块的电压竞争) Frit...
图中风扇部分电路(继电器负载部分)所标注的GND/5V 可以通过外接电源供电;也可以直接在单片机上的某对GND/VCC上。 风扇的可用性调试 风扇需要足够的电压来驱动,一般就接在5v(vcc/gnd) 但是风扇可以产生反电动势,对单片机可能造成损害,所以一般其中的一个管脚接在继电器的负载部分(您可以通过led等来调试继电器的可用...
