Motoren per Bluetooth ansteuern

[Anonym]

Über USB funktioniert mein Programme gut, muss ich es für Bluetooth wie folgt abändern ?

 #include <SoftwareSerial.h>
 
char val;
const int pwmA = 3;
const int pwmB = 11;
const int brakeA = 9;
const int brakeB = 8;
const int dirA = 12;
const int dirB = 13;
 
int bluetoothTx = 2;
int bluetoothRx = 4;
SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
 
void setup() {
  pinMode(dirA, OUTPUT);
  pinMode(brakeA, OUTPUT);
   
  pinMode(dirB, OUTPUT);
  pinMode(brakeB, OUTPUT);
 
  Serial.begin(115200);       
}
 
void loop() {
{
    if (bluetooth.available())
    {
      Serial.print((char)bluetooth.read());
    }
    if (Serial.available())
    {
      bluetooth.print((char)Serial.read());
    }
  }

  if ( val == 'S' )
   
     {
       digitalWrite(pwmA, 255);
       digitalWrite(dirA, LOW);
       digitalWrite(brakeA, LOW);
 
 
       digitalWrite(pwmB, 255);
       digitalWrite(dirB, HIGH);
       digitalWrite(brakeB, LOW);
     }
    delay(100);
 
  if (val == 'W') {
 
    digitalWrite(pwmA, 255);
    digitalWrite(dirA, LOW);
    digitalWrite(brakeA, LOW);
 
 
    digitalWrite(pwmB, 255);
    digitalWrite(dirB, HIGH);
    digitalWrite(brakeB, LOW);
 
    Serial.println("Vorwaerts 100%.");
  }
 
 
  delay(100);
  if (val == 'S') {
 
    digitalWrite(pwmA, 255);
    digitalWrite(dirA, HIGH);
    digitalWrite(brakeA, LOW);
 
    digitalWrite(pwmB, 255);
    digitalWrite(dirB, LOW);
    digitalWrite(brakeB, LOW);
 
    Serial.println("Rueckwaerts 100%.");
 
  }
  delay(100);
  if (val == 'A') {
 
    digitalWrite(pwmA, 255);
    digitalWrite(dirA, LOW);
    digitalWrite(brakeA, LOW);
 
    digitalWrite(pwmB, 255);
    digitalWrite(dirB, LOW);
    digitalWrite(brakeB, LOW);
 
    Serial.println("Nach links drehen");
 
  }
  delay(100);
  if (val == 'D') {
 
    digitalWrite(pwmA, 255);
    digitalWrite(dirA, HIGH);
    digitalWrite(brakeA, LOW);
 
    digitalWrite(pwmB, 255);
    digitalWrite(dirB, HIGH);
    digitalWrite(brakeB, LOW);
    Serial.println("Nach rechts drehen");
 
  }
    if (val == '0') {
 
    digitalWrite(pwmA, 0);
    digitalWrite(pwmB, 0);
 
    Serial.println("Motoren aus");
 
  }
}
