【iam学代码】模拟串口读取

iam郎

1. /*
   
2.   AnalogReadSerial
   
3.   Reads an analog input on pin 0, prints the result to the serial monitor.
   
4.   Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
   
5. 模拟串口读取程序，读取A0接口的数据，然后在串口监视器上显示结果。把滑动变阻器的中间脚
   
6. 接到A0脚上，其余的接口分别接地gnd和5v
   
7. 
   
8. This example code is in the public domain. 公开的

18. void loop() {
    
19.   // read the input on analog pin 0:
    
20.   int sensorValue = analogRead(A0);
    
21.   // print out the value you read:
    
22.   Serial.println(sensorValue);
    
23.   delay(1);        // delay in between reads for stability
