FORGET EVERYTHING!! Ok I have 2 motors DC that´ll work at 9V (inputs) controlled from the pins of the Arduino and the integrated circuit LM293D (throughole version). The Arduino will run this code: //Motor1 int IN1 = 9; int IN2 = 8; int ENA1 = 10; // Motor 2 int IN4 = 6; int IN3 = 5; int ENA2 = 3; int speedmotor = 127; //1=Hacia delante, 2=Hacia atrás, 3=Giro izquierdas, 4=Giro derechas int movimiento = 0; int movAnterior = -1; bool estado = true;

//Bluetooth(incluir libreria y softwareserial)

void setup() { Serial.begin(9600); pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT); pinMode(ENA1, OUTPUT); pinMode(IN3, OUTPUT); pinMode(IN4, OUTPUT); pinMode(ENA2, OUTPUT); //Se imprime un texto cada vez que se conecte Serial.println("CONTROL INALAMBRICO CONECTADO "); } void loop() { if(Serial.available()){ //Digo al Arduino que lea si el valor almacenado es mayor a 0 movimiento = Serial.parseInt(); //devuelve un numero entero y lo soobreescribe en la variable de movimiento } if(movimiento != movAnterior){ movAnterior = movimiento;

if(movimiento == 0){ Serial.println("Coche Detenido"); digitalWrite(IN1, 0); digitalWrite(IN2, 0); digitalWrite(IN3, 0); digitalWrite(IN4, 0); analogWrite(ENA1, 0); analogWrite(ENA2, 0); estado = true; } if(movimiento == 1){ Serial.println("Ir hacia adelante: "+String(speedmotor)); digitalWrite(IN1, 1); digitalWrite(IN2, 0); digitalWrite(IN3, 0); digitalWrite(IN4, 1); analogWrite(ENA1, speedmotor); analogWrite(ENA2, speedmotor); estado = true; } else if(movimiento == 2){ Serial.println("Ir hacia atras: "+String(speedmotor)); digitalWrite(IN1, 0); digitalWrite(IN2, 1); digitalWrite(IN3, 1); digitalWrite(IN4, 0); analogWrite(ENA1, speedmotor); analogWrite(ENA2, speedmotor); estado = true; } else if(movimiento == 3){ Serial.println("Girar hacia la derecha: "+String(speedmotor)); digitalWrite(IN1, 1); digitalWrite(IN2, 0); digitalWrite(IN3, 1); digitalWrite(IN4, 0); analogWrite(ENA1, speedmotor); analogWrite(ENA2, 0); estado = true; } else if(movimiento == 4){ Serial.println("Girar hacia la izquierda: "+String(speedmotor)); digitalWrite(IN1, 0); digitalWrite(IN2, 1); digitalWrite(IN3, 0); digitalWrite(IN4, 1); analogWrite(ENA1, 0); analogWrite(ENA2, speedmotor); estado = true; } Serial.println("movimiento: "+String(movimiento)); if(movimiento == 5 && estado == true){ Serial.println("speedmotor antes de cambiar: "+String(speedmotor)); speedmotor = speedmotor - 50; speedmotor = constrain(speedmotor, 10, 255); Serial.println("speedmotor despues de cambiar: "+String(speedmotor)); analogWrite(ENA1, speedmotor); analogWrite(ENA2, speedmotor); delay(500); estado = false; } else if(movimiento == 6 && estado == true){ Serial.println("speedmotor antes de cambiar: "+String(speedmotor)); speedmotor = speedmotor + 50; speedmotor = constrain(speedmotor, 10, 255); Serial.println("speedmotor despues de cambiar: "+String(speedmotor)); analogWrite(ENA2, speedmotor); analogWrite(ENA1, speedmotor); delay(500); estado = false; } delay(1000);

} } It is design to run bassed on a 9V 2100mAh battery. There will also be a bluetooth model (HC-04) that will be connected to a mobile phone that through an APP will send the respective number (1 or 2 or 3... depending on what the user want to do at that moment) put all the respective resistors and capacitors that you consider necessary but everything throughole please
