大佬们,萌新问个问题..就是我在做一个小车,然后我想不用拓展板,就用uno板来实现电机的正转与反转,然后我在网上就查到了一个4个开关的电路能实现正反转,所以我想能否用2个引脚的高低电压差来模拟开关的开和闭
你真的搞懂了Arduino的HIGH和LOW吗?多大的电压是高电平HIGH?多小的电压是低电平LOW?耳听为虚眼见为实。直接通过digital Write D2 HIGH和digital Write D4 LOW然后用万用表量一下电压可以看到,输出HIGH是大于4v输出LOW是接近0v再来看看输入的情况这里用一台开关电源
在Arduino中,HIGH和LOW分别代表什么电平?() A. HIGH代表5V,LOW代表0V B. HIGH代表3.3V,LOW代表0V C. HIGH代表
例如:boolean output = HIGH;
Many effective and high-performing systems have been created, but they are often expensive, complex, and difficult to establish. We developed a system that is similarly high performing, but at a low cost and with a simple and accessible design. This system is controlled by an Arduino Nano, ...
