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
A. HIGH代表5V,LOW代表0V B. HIGH代表3.3V,LOW代表0V C. HIGH代表0V,LOW代表5V D. HIGH代表-5V,LOW代表5V相关知识点: 试题来源: 解析 A 反馈 收藏
例如:boolean output = HIGH;
一、DIGITAL SIGNALS AND HIGH STATE 在讨论数字信号时,理解HIGH和LOW的概念是至关重要的。数字信号与我们日常生活中的开关操作有着直接的类比关系。当一个开关被打到ON位置时,电路被闭合,通电;这在数字电子学中相当于一个HIGH状态。与此相对的是,当开关被打到OFF位置,电路被断开,切断电流;这在数字电子学中对应...
Of course, that hasn’t stopped us from controlling much larger devices like gear motors and large stepper motors. We accomplished this by using a driver board to take the low-current Arduino control signals and drive the high-current motors. In these cases, the driver board did all of the...
Thanks to its industrial-grade sensing capabilities, it is suitable for asset tracking, object recognition and predictive maintenance. Quickly implement sensor nodes to send collected data to the Arduino Cloud (or third-party vendor services) via integrated WiFi/Bluetooth Low Energy connectivity. ...
Arduino pulseIn: Pulsein Measures high or low periods of a signal in microseconds. Why is your pulseIn measurement inaccurate - Find out here. Why does one function need interrupts On, while the other one needs them Off? There are two functions pulseIn and pulseInLong... Find out the ...
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, ...
