Arduino – BLUETOOTH & ANDROID PIR ALARM with call and sms Functions!

Hello world! Today i made a android app that communicates with a arduino using the HC-06 Bluetooth module for a PIR Motion sensor GSM Alarm. You can set 1 phonenumber to the DATABASE that needs to be called when movement is detected. When movement is detected it will call you and you can listen what is happening in your home, If you missed the call you can send a SMS with the command “Call me” (it is case sensitive, so use capital C). You can also send a SMS command with “Disconnect” and the bluetooth module will disconnect. For the Schematic, Arduino Code, Android APP & Parts list follow the next link: http://www.instructables.com/id/Arduino-BLUETOOTH-ANDROID-PIR-ALARM-With-Call-and-/

NOTE: You need to take a few steps for the APP to operate properly and you need to connect the Phone to a Charger.

Follow these next steps on your Android phone.
1: Settings, go to call, extra settings, turn off proximity sensor.
(Turns off screen during calls when on, and we want the screen to be on)

2: Settings, Location & security, setup screen lock to none.

3: Settings, Applications, development, turn on standby or might be named stay awake on your phone
(keeps screen on during Charging)

Arduino Tutorial – LCD Display Control via Bluetooth (Part2)

How to control an LCD via Bluetooth

First watch this video:

Hardware Required

– Arduino or Genuino Board
– LCD Screen
– HC06-05 Bluetooth Module
– Pin headers to solder to the LCD display pins
– 10k ohm potentiometer
– 220 ohm resistor
– hook-up wires
– breadboard

The LCDs have a parallel interface, meaning that the microcontroller has to manipulate several interface pins at once to control the display. The interface consists of the following pins:

– A register select (RS) pin that controls where in the LCD’s memory you’re writing data to. You can select either the data register, which holds what goes on the screen, or an instruction register, which is where the LCD’s controller looks for instructions on what to do next.
– A Read/Write (R/W) pin that selects reading mode or writing mode
– An Enable pin that enables writing to the registers
– 8 data pins (D0 -D7). The states of these pins (high or low) are the bits that you’re writing to a register when you write, or the values you’re reading when you read.
– There’s also a display constrast pin (Vo), power supply pins (+5V and Gnd) and LED Backlight (Bklt+ and BKlt-) pins that you can use to power the LCD, control the display contrast, and turn on and off the LED backlight, respectively.

Circuit

Before wiring the LCD screen to your Arduino or Genuino board we suggest to solder a pin header strip to the 14 (or 16) pin count connector of the LCD screen.
To wire your LCD screen to your board, connect the following pins:

LCD VSS pin to Arduino GND
LCD VDD pin to Arduino 5V
LCD RS pin to digital pin 12
LCD RW pin to Arduino GND
LCD Enable pin to digital pin 11
LCD D4 pin to digital pin 5
LCD D5 pin to digital pin 4
LCD D6 pin to digital pin 3
LCD D7 pin to digital pin 2
Additionally, wire a 10k pot to +5V and GND, with it’s wiper (output) to LCD screens VO pin (pin3).
A 220 ohm resistor is used to power the backlight of the display, usually on pin 15 (A+) and 16 (K-) of the LCD connector.

1/2 ANDROID Bluetooth модуль HC-05 Управление без without Arduino AT Commands Часть 1.

Часть 1. Управление по Bluetooth, без использования Arduino или других микроконтроллеров,
только с помощью двух Bluetooth модулей HC-05, через AT Commands.

Для чего это нужно? например для управления люстрой, включать выключать лампочки люстры с помощью ANDROID телефона по Bluetooth.

sketch Arduino – Bluetooth HC-05 – AT Commands – TEST
http://yadi.sk/d/zSV0Ca0tHfHgK

sketch Arduino-Bluetooth HC-05-AT Commands-Atmega-TEST
http://yadi.sk/d/fJJs1r0IHfHwi

Если сложновато, посмотрите для начала мой видео уроки

Configuring The HC-05 Bluetooth Module with AT Commands Arduino поменять имя и пароль

Arduino и Bluetooth модуль HC-05 Wireless Bluetooth RF Transceiver Module RS232 TTL

Управление люстрой v.01 Android + Arduino Bluetooth HC-05 Wireless remote control

программа “Voice Control Bluetooth HC05” .
https://play.google.com/store/apps/details?id=appinventor.ai_g916414.Voice_Control_Bluetooth_HC05

что нам понадобится? 2 Bluetooth модуля HC-05 + реле для управления нагрузкой 220 вольт, и программа “Voice Control Bluetooth HC05” .

Какой принцип работы ? у Bluetooth модуля HC-05 имеются 7 свободных pins это 10й и с 2 по 7й pin,
когда мы подаём положительный сигнал +3v на 11й pin то Bluetooth модуль HC-05 переходит в режим AT Commands,
в этом режиме “AT Command” посылая на serial вход “RX” соответствующие команды мы можем менять состояния pins, с + , на – , например послав команду “AT+PIO=10,1” 10й pin изменит своё состояние на +, а если послать “AT+PIO=10,0” 10й pin изменит своё состояние на – , также и другие pins “AT+PIO=7,1” “AT+PIO=7,0” команда “AT+MPIO=CFC” включает все pins, а “AT+MPIO=0″ выключает все pins.
Важно отметить все команды должны иметь в конце невидимые ! символы ” обозначаются “rn” оно же “LF и CR” , что такое rn “LF и CR”?

Так как для управления люстрой мы не будем использовать микроконтроллер например ATmega328 или плату Arduino,
а Bluetooth модуль HC-05 в режиме программирования “AT Command” не может принимать команды по Bluetooth,
то мы будем управлять им с помощью другого Bluetooth модуль HC-05 по serial,
то есть, посылая команды от ANDROID телефона по Bluetooth с помощью программы “Voice Control Bluetooth HC05”
на “Bluetooth модуль HC-05” (назовем его №1) через serial выход “TX” будем перенаправлять эти команды на вход “RX” “Bluetooth модуля HC-05” (назовем его №2) который будет находится в режиме программирования “AT Command”.

Примеры AT команд.

AT+VERSION? узнать версию прошивки.

AT+UART? узнать установленную скорость.

AT+UART=38400, 0,0 установить скорость 38400.

AT+PIO=10,1 включить 10й pin.
AT+PIO=7,1 включить 7й pin.

AT+PIO=10,0 выключить 10й pin.
AT+PIO=7,0 выключить 7й pin.

AT+MPIO=CFC включить все pins.
AT+MPIO=0 выключить все pins.
AT+MPIO=C24 включить (10й , 5й , 2й. pins).

сначала включив pins например (10й , 5й , 2й. pins) надо отправить команду
AT+MPIO? serial монитор выдаст в ответ команду C24 желательно отправить несколько раз команду AT+MPIO?
эта опция с первого раза работает некорректно, теперь отправляя команду AT+MPIO=C24 мы включим (10й , 5й , 2й. pins).

AT+NAME? узнать имя.
AT+NAME=HC-05 BLUE установить имя HC-05 BLUE.

AT+PSWD? узнать пароль.
AT+PSWD=0000 установить пароль 0000.

AT+ORGL сброс на заводские настройки – Restore the default setting .

project Description:
Google android operating system is one of the leading and most popularly preferred systems in smart phone. Smart phone affordability increases day by day due to their size and portability .android GUI installed in smart phone. The operator has to touch on the screen of the phone to control the home appliances. This project is an android application which possesses the capability to control any sort of electrical appliances providing remote access from smart phone using Bluetooth. Bluetooth technology is wireless radio transmissions in a short distance providing a necessary technology to create convenience, intelligence and controllability. This generates personal area network in home environment, where all these appliances can be interconnected and monitored using a single controller. Home automation involves a degree of computerized or automatic control to certain electrical and electronic systems in a building. Busy families, individuals with physical limitation represent very attractive market for such networking. This system will also assist and provide support in order to fulfill the needs of elderly and disabled in home

The Bluetooth antenna in our module picks up the packets sent from the cell phone. Subsequently, these packets containing the appliance status commands are pipelined through ATmega328 microcontroller and the designed analogue circuitry according to the definition of each output. Different home appliances are connected to the digital output ports of the arduino BT board via relays to provide sufficiently high currents and voltage compatibility. For test purposes, 25W, 240V lamps have been used. Figure 2 shows the relay configuration for each device and Figure 3 depicts the arduino BT board‟s communication with the home appliances. Sending commands from software to turn ON/OFF a device may not guarantee the successful operation of the device as the device may be defective. To solve this problem, a feedback circuit has been designed and implemented to indicate the device‟s actual status after it receives the command (ON/OFF) from the cell phone. Once the command has been sent to turn ON a device, the feedback circuit senses the current and gives an output signal by turning ON a respective led on the switching circuitry indicating that the device is ON. Otherwise, the device is malfunctioning indicating that the command was not executed successfully.
