Hi,
Here is my program where i can control a servo and a dc motor, but only the servo is ok,
when i send 2 on my bluetooth nothing happen..
#include <SoftwareSerial.h> // TX RX software library for bluetooth
#include <Servo.h> // servo library
Servo myservo; // servo name
int cmd;
int bluetoothTx = 10; // bluetooth tx to 10 pin
int bluetoothRx = 11; // bluetooth rx to 11 pin
int E1 = 5;
int M1 = 4;
SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
void setup()
{
myservo.attach(9); // attach servo signal wire to pin 9
//Setup usb serial connection to computer
Serial.begin(9600);
pinMode(M1, OUTPUT);
//Setup Bluetooth serial connection to android
bluetooth.begin(9600);
}
void loop()
{
//Read from bluetooth and write to usb serial
if(bluetooth.available()> 0 ) // receive number from bluetooth
{
cmd = bluetooth.read(); // save the received number to servopos
Serial.println(cmd); // serial print servopos current number received from bluetooth
myservo.write(cmd); // roate the servo the angle received from the android app
if(cmd == '2') //Checks whether value of Incoming_value is equal to 1
digitalWrite(M1,HIGH);
analogWrite(E1, 255);
if(cmd == '0') //Checks whether value of Incoming_value is equal to 0
digitalWrite(M1,LOW);
analogWrite(E1, 0);
}
}
