MIT Codes

Below are the Arduino codes 

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); Bluetooth  module connected to 2,3 pins of ardiuno

#define relay1 A1

#define relay2 A2

#define relay3 A3

#define relay4 A4

char val;

void setup() {

pinMode(relay1,OUTPUT);

pinMode(relay2,OUTPUT);

pinMode(relay3,OUTPUT);

pinMode(relay4,OUTPUT);

digitalWrite(relay1,LOW);

digitalWrite(relay2,LOW);

digitalWrite(relay3,LOW);

digitalWrite(relay4,LOW);

mySerial.begin(9600);

Serial.begin(9600);

}

void loop() {

//cek data serial from bluetooth android App

while ( mySerial.available() >0 ) {

val = mySerial.read();

Serial.println(val);

}

//Relay is on

if( val == '1' ) {

digitalWrite(relay1,HIGH); }

else if( val == '2' ) {

digitalWrite(relay2,HIGH); }

else if( val == '3' ) {

digitalWrite(relay3,HIGH); }

else if( val == '4' ) {

digitalWrite(relay4,HIGH); }

//relay all on

//relay is off

else if( val == 'A' ) {

digitalWrite(relay1,LOW); }

else if( val == 'B' ) {

digitalWrite(relay2,LOW); }

else if( val == 'C' ) {

digitalWrite(relay3,LOW); }

else if( val == 'D' ) {

digitalWrite(relay4,LOW); }

//relay all off

}

ATS (Auto Transfer Switch ) with 3 sources input

 ATS (Auto Transfer Switch ) with 3 sources input

The clasical ATS system already shared by every one ,  but now a days we may need 3 thource ATS type through which we can manage the sources like hybrid power system   Mains power supply  , Generators, Solars , inverters ,  

If we look at the figure first of all source (S-1) will be connected as the relay will be energized through transformer which is connected to the Source (S-1), 

Failure of Source (S-1)  relay will not in the energized position , where common pin will be connected to relay (NC) pin , here NC pin is connected to the relay 2 common pin , 

If source (S-2 ) available relay 2 will be energized common pin will be connected to relay 2 (NO) ,

source (S-2) will be connected through NO pin then to Common of relay 2 ,then to NC of Relay 1 finally to output.

If source (S-2 ) unavailable relay 2 will be off , source (S-3) will be connected through NC of relay 2 then common pin then to the  NC or relay 1 finally to the output.

SIMPLE IDEA

How to Use External Microphone on Android Phones

Using any Android phone for recording video or audio it will not allow you to use external microphone or line input , but with simple modification you can enable the external microphone 

just by adding 6.8k resistor to both microphone wires will mute the internal microphone , and enable for external source inputs.

In video voice recorder were used for testing , internal microphone still found enabled while inserting the jack, 

But by adding resistor found that internal microphone disabled

Arduino Bluetooth Remote Control (Updated )

Arduino Bluetooth  Remote Control

Output taken from Ardiuno 2 & 4 pins, Bluetooth device connected at 6 & 7 pins

For 30Amps Relay 2SC1384 used connected to pin 2, C945 for 10 Amps Relay connected to pin 4 . In Android application Buttons 1 & 3 will work.

Search Bluetooth device first enter 0000 password, 

Now start app in Android  press connection button ,it will be green  below it show the connection status 

Then you on or off any Appliances
