Arduino Bluetooth RC 4 Channel APK

Funcionamento do aplicativo apenas com dispositivos conectados via bluetooth;
Observe que o led do módulo bluetooth(JY MCU) estava piscando e quando está conectado para de piscar e fica aceso direto;

Vejam em meu blog outros vídeos, fotos e programa para Arduino utilizado no projeto com

Description:

Operation of the application only with connected devices via bluetooth;

Walkthrough:

1 - Re-assemble the proto board as electric scheme;
2 - Connect the bluetooth (JY MCU) and Arduino module, see the LED is flashing;
3 - In Smartphone turn Bluetooth on and enter the Arduino Bluetooth RC 4 Channels application and press the Connect button;
4 - Note that the bluetooth module LED (JY MCU) and was blinking when connected to flashing and stay straight on;
5 - The devices are conetctados via bluetooth - Direct LED is lit.

6 - At this time all application buttons work and send data to the bluetooth module and the Arduino.


 The Arduino Bluetooth RC 4 Channels application installed on your smartphone remotely controls the Arduino (via bluetooth) with 4 channels (digital port pin 4, pin 5, pin 6, pin 7);

Through these pins can connect a board with 4 relays, and power up to 4 devices handled residential power grid;
Control the drive (league and deslida) lamps, abatjours, fixtures, motors, pumps, solenoids, contactors, electric oven, appliances, etc..

Use a smartphone with android to install this "apk.", In this example we used the Samsung Galaxy Tablet GT-P3100 Tab2 7.0 "with android version 4.0.

About configuring the Bluetooth module JY_MCU.
This module comes factory configured with:
Baud rate: 9600 bps;
Data bits: 8 bits;
Stop bits: 1, Parity: none;
Summary (9600 bps, 8N1);


We can see that when you press the "ON - CH1" button an image of the lamp illuminates (yellow) along with the led the drive relay that is connected to the Arduino (digital pins 4, 5, 6 and 7) and when you press plate "OFF - CH1" button turned off the lamp (transparent color) Android Smartphone and simultaneously led the drive relay board goes.

Note: The drives (CH1, CH2, CH3 and CH4) can act independently or simultaneously, facilitating their operation and opening multiple possibilities in residential automation as an example where you need to trigger the Luminaris of cozy, living rooms, bedrooms, halls, cooking, smarter.

How the circuit works:
The Arduino Bluetooth RC 4 Channels application installed on Android Smartphone with communicating with the bluetooth which is connected to the serial (mySerial) pin 2 and 3-RX-TX Arduino that receives data entities which in turn, interprets and makes the relay control (card drive relay) that is connected to the digital port corresponding (Arduino pins 4, 5, 6 and 7).


Warning: When working with this application keep the screen always on (do not use sleep mode or sleep) because you may lose control of the device being powered.

Note: To exit the application, always check before if the buttons are in the "OFF" mode - lamp off then press the "disconnect" button and exit the application; Note that the bluetooth will flash indicating that the system is actually disconnected.

About data transmission:
When pressed by example "CH1 - ON" button transmits your smartphone via bluetooth the character "A" and the Arduino puts high logic level (1) that turns on the LED digital pin 4;
When pressed by example "CH1 - OFF" button transmits your smartphone via bluetooth "B" character poses and the Arduino logic level low (0), which makes clear the LED digital pin 4;

This is all you need to know to build your program:
CH1 button - ON - send: "A" character; CH1 button - OFF - send: character "B";
CH2 button - ON - send: character "C" CH2 button - OFF - send: character "D";
CH3 button - ON - send: character "E"; CH3 Button - OFF - send: character "F";
CH4 button - ON - send: character "G"; CH4 Button - OFF - send: character "H";
