单独的脚本以读取和写入arduino

Question

我有2个脚本，一个用于将数据发送到arduino，另一个用于从arduino接收数据。当执行接收脚本时无法产生预期的结果。

# script1 code fro sending data to arduino
arduinoData = serial.Serial('/dev/ttyACM1', 115200)
while i < 3:
    print('started recording')
    arduinoData.write('1')
    time.sleep(2)
    print('start rotating')
    x = datetime.datetime.now().time()
    t1 = ((float(x.hour) * 3600) + (float(x.minute) * 60) + 
float(str(x.second) + '.' + str(x.microsecond)))
    ti.append(t1)
    time.sleep(2)
    print('end')
    time.sleep(2)
    arduinoData.write('0')
print('over')



# script2 code for recieving data from arduino:
arduinoData = sl.Serial('/dev/ttyACM1', 115200)  # Creating our 
serial object named arduinoData
while (arduinoData.inWaiting() != 0):  
while i < 3:
    arduinoString = arduinoData.readline()
    x = datetime.datetime.now().time()
    if (arduinoString != '1'):
        data = int(arduinoString)            
        val.append(data)                     
        t1 = ((float(x.hour) * 3600) + (float(x.minute) * 60) + float(str(x.second) + '.' + str(x.microsecond)))
        time.append(t1)
    else:
        t.append(time)
        v.append(val)
        print(t)
        print(v)
        val.clear()
        time.clear()
        i += 1
# arduino code:
void setup()
{

Serial.begin(115200); //turn on serial monitor
}

void loop() 
{
  if (Serial.available()){
         if(Serial.read() == '0') {
          Serial.println('1');
            }
          else if(Serial.read()== '1') {
            raw = analogRead(analogPin);
            Serial.println(raw); 
           }}
           else
          {
           raw = analogRead(analogPin);
           Serial.println(raw); 
            }


  }

结果应打印出列表t和v。运行脚本时，脚本2终止，并在脚本1终止后继续运行evnen。那是它不会进入其他部分。我不知道为什么？请帮我。 有时在运行python错误时如下 无法将字符串转换为int。 请提供建议
