Week 8 - Journal

firstly I defined the buzzer is on pen 4 and enable pen of motor 9 and transSpeed 9600 off 0 on 1 and appdata=0

and begin in void set up and defined pens as it is output so in void loop tell to arduino if appdata >0 go to the input and read... if appdata =A OR a set the buzzer on if appdata=B or b set the buzzer off,, if appdata=1 set the motor on,, if appdata=2 set the motor off..

then I go to cheek wiring so it's wired as:

1- H-bridge first output connect to the motor and enable to pen9 and inputs 7,8 it has 2 power 1=5V for IC to open and 2=9v for motor and ground

2-buzzer on pen 4

3- Bluetooth module 4 pens 1=5v,2=GRD ,, TXD,RXD=0,1

to control with system from mobile application first you must open Bluetooth from mobile settings and connect with HC-05

And open application and connect with module HC-05 and go setting of app and from command buttons configuration configure data to send and set Button A as A, Button B as B,, Button C as c... Button D AS 1.... Button E as 2...Button F as 3

then upload the code on Arduino board and controlled

the code :

//pin 9 and 6 target, to use the pwm signal

#define Bazzer 4

#define MOTOR 9

#define TransSpeed 9600

#define OFF 0

#define ON 1

char AppData = 0;

void setup()

{

Serial.begin(TransSpeed);

pinMode(Bazzer, OUTPUT);

pinMode(MOTOR, OUTPUT);

pinMode(7, OUTPUT);

pinMode(8, OUTPUT);

}

void loop()

{

if(Serial.available() > 0)

{

AppData = Serial.read();

Serial.print(AppData);

Serial.print("\n");

if (AppData == 'A' || AppData == 'a')

digitalWrite(Bazzer, ON);

if (AppData == 'B' || AppData == 'b')

digitalWrite(Bazzer, OFF);

if (AppData == '1')

{

analogWrite(MOTOR,180);

digitalWrite(7,HIGH);

digitalWrite(8,LOW);

}

if (AppData == '2')

{

analogWrite(MOTOR,0);

digitalWrite(7,HIGH);

digitalWrite(8,LOW);

}

}

}
