To bring up the serial terminal and view its output, go to Tools >> Serial Monitor in the IDE. You should see something like this show up in the resulting serial console: Hello world! You can also move the second line of code to the ‘loop’ function so that it will be executed ...
上传代码后,打开Serial Monitor,监视器将询问位于1-127之间的指纹ID 。 现在Serial Monitor显示屏中输入ID号,并发送,然后按照屏幕指令提示录入指纹。 把希望录入的手指放在传感器上。 一个手指录入成功后,你也可以按照同样的方式再录入其他几个手指的指纹。 指纹读取代码如下: #include int u=0; int relay=5; #i...

Reads an analog input on pin 0, converts it to voltage, and prints the result to the Serial Monitor. Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu). Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. ...
演示如何使用模拟引脚读取来自某个传感器的输入：The following is a simple Arduino example. Demonstration of how to use analog pins to read the input from a sensor:```cpp// 定义一个变量来存储读取的值int sensorValue = 0;void setup() { // 初始化串口，设置波特率为9600 Serial.begin(9600);...
Serial.println(sensorValue); 现在,当你打开Arduino IDE的串口监视器,你会看见“0”的数据流(如果开关打开)或者“1”的数据流(如果开关闭合) /* DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public domain. ...
