Introduction: CONTROL YOUR HOME LIGHTING WITH ANDROID
Tecnology progressing is so fast. Now smartphone not just used as a communication, but smartphone can be used to control your home lighting. In this intruction we will see how to use Arduino control lights of your home.
To make this project, we will need :
Hardware
1. Arduino UNO
2. Relay Module
3. Bluetooth Module
4. Smarthphone
5. LED
6. Cable
7. Plug
8. Fitting Lamp
Software
1. Arduino IDE
2. Bluetooth Controller
How to work?
Step 1: Connecting Module Bluetooth With Arduino
1. Connect VCC with 3.3 volt of Arduino
2. Connect GND with GND of Arduino
3. Connect Rx pin with Tx of Arduino
4. Connect Tx pin with Rx of Arduino
Step 2: Connecting Relay With Arduino
1. Connect VCC with VCC 5V of Arduino
2. Connect GND with GND of Arduino
3. Connect port in with pin 10 of Arduino
Step 3: Connecting Relay With Lamp
1. Connect port Common of Relay with AC Voltage source
2. Connect port NO of Relay with lamp
Step 4: Control Lamp (On/Off) Used Arduino Serial Monitor
#include <Bluetooth_HC05.h>
int state;
int flag=0;
int stateStop=0;
void setup() {
pinMode(10, OUTPUT);
Serial.begin(9600);
}
void loop() {
if(Serial.available() > 0)
{
state = Serial.read();
flag=0; if (state == 'A')
{
digitalWrite(10, LOW);
}
if (state == '1')
{
digitalWrite(10, HIGH);
}
if (state == '2')
{
digitalWrite(10, LOW);
}
}
}
Step 5: Connecting HC-05 Bluetooth Module With Smartphone
1. Arduino must be On condition
2. Download “Bluetooth Controller” app from Play Store
3. Open “Bluetooth Controller” app
4. Choose “HC-05” and enter code ”1234/0000”
5. After connected tap “set keys” and content keyname
Example : Lamp ON / Lamp OFF
Then content of key data as the program
Step 6: ON / OFF Lamp With Smartphone
If we want to ON tap key Lamp ON and if we want OFF we can tap Lamp OFF smartphone.
