Android app to control 4 channel relay modul with Arduino via bluetooth

Arduino Bluetooth Relay 4CH App is android application which is used to control 4 channel relay module via Bluetooth with Bluetooth serial communication module support HC-05, HC-06, or HC-07, Using Arduino or AVR

i am test with arduino UNO and serial commnunication library to connected RX pin 10 and TX pin 11.

you can use arduino uno or arduino leonardo etc...

Fitur App:

-control 4 channel on/off ralay

-control All channel ON

-control All channel OFF

-download file Program Arduino_Bluetooth_Ralay_4ch.ino

-download file Tutorial PDF with schemmatic

Download File:

-arduino project ZIP : https://goo.gl/Vq1n9D

-tutorial & schematic wiring PDF : https://goo.gl/b2UVY1

or you can

Copy program here to Arduino IDE

/*

Relay IN1 connected to PinOut 2 Arduino

Relay IN2 connected to PinOut 3 Arduino

Relay IN3 connected to PinOut 4 Arduino

Relay IN4 connected to PinOut 5 Arduino

--->you can connected to relay modul 4 channel

Serial data sending from Arduino Bluetooth Relay 4CH.apk

data '1'-'4' to on is Ralay CH 1-4

data 'A'-'D' to off is Ralay CH 1-4

data '9' to on ALL CH 1-4

data 'I' to off ALL CH 1-4
