setup()函数在Arduino板复位后只运行一次。 Serial.begin(9600);初始化串行通信,设置波特率为9600。波特率是串行通信的速度,9600表示每秒传输9600个数据位。 3.loop()函数 void loop() { // read the input on analog pin 0: int sensorValue = analogRead(A0); // Convert the analog reading (which goes ...
Arduino系列研究中，我们关注了Arduino IDE内置的丰富示例，包括模拟输入与串口输出的示例AnalogInOutSerial。这些示例共有11个分类，旨在帮助初学者理解和实践各种功能，如模拟读取、数字串口通信等。在本篇中，我们将深入剖析0017号示例，即如何通过模拟输入读取数据，并将结果通过串口输出，控制LED的亮度变化。
Arduino溶液检测传感器-Analog ORP Meter 模拟ORP计概述想DIY一个ORP计吗?还在为没有一款价格低廉、使用方便的ORP计而烦恼吗?我们推出了一款专为Arduino控制器设计的模拟ORP计,具有连线简单、方便实用等特点。按照示意图连线后,再通过程序控制,就可以非常方便的测量溶液的ORP。 ORP是英文Oxidation-Reduction Potential的...
Serial.print("\t"); Serial.println(yValue); } Mapping It is usually not enough to read the analog values, you might want to map it to a display or any other interface. So let's map these these values to a 8x8 led matrix. So that we can move the pixel with the joystick. You ...
