你如果不用考虑时序问题，也不用考虑传输速度以及类似干扰、滤波等等杂七杂八的问题和需要，这样是没问题...
UNO板,LM35温度传感器网上看了段代码,... pinMode(A0,OUTPUT)...temp = analogRead(A0)想请问为什么将传感器输出口连接的A0设置为OUTPUT?这里不是用作数据输入吗,应该是INPUT把?不过我试了一下设置为OUTPUT和INPUT获取的数值差不多。是不是模拟口在没有Write过数据前设置IN/OUT没有差别呢?请问是什么原理。附上...

For example, those familiar with Arduino Uno boards will immediately recognize that analog inputs (analogRead) can range from 0-1023. Analog outputs (analogWrite) can range from 0-255. For PLCs such as the Siemens S7-1200, analog inputs (used in a normX command) and outputs (used in a...

We will also look at a way to “see” the analog input as the Arduino sees it, wrapping up the chapter with methods for mapping these values to more usable forms. What’s needed for this chapter: • Arduino Uno • Modern Device MD0550 wind sensor • 2N2222 or 2N3904 NPN ...
