How To Make Arduino Based Home Automation Project via Bluetooth?

Circuit Diagram

ส่วนHardware (input,Output)

1.Bluetooth Module:

The Bluetooth Module used in this project is HC- 05. As seen in the image below, this Bluetooth module has 4 – pins for VCC (5V), ground, TX and RX.

This Bluetooth can be used with Bluetooth enabled phone (or tablet or laptop) and the range of this module is approximately 10 meters.

2. 4-Channel Relay Board:

A 4 – channel relay board is used in this project to control four different loads. It has all the necessary components and connections like base current limiting resistor, flyback diode, LED indicators and header for connecting it to other devices.

Caution: We should be very careful when using a relay with AC mains.

Code

	ส่วนหัวโปรแกรม #include <SoftwareSerial.h> //ฟังชั่นพิเศษ กำหนม library ที่เราเรียกใช้งาน
	const int rxPin = 4; //กำหนดตัวแปร rxPin = ขา 4
	const int txPin = 2; //กำหนดตัวแปร rxPin = ขา 2
	SoftwareSerial mySerial(rxPin, txPin);
	const int Loads[] = {9, 10, 11, 12};
	int state = 0;
	int flag = 0;
	ส่วนตัวโปรแกรมมี 2 ส่วน
	1.void setup() //เป็นฟังชั่นแรกเมื่อ Arduino ทำงาน
	{
	for (int i=0;i<4;i++) //สั่งให้ทำซ้ำไปเรื่อยๆ
	{
	pinMode(Loads[i], OUTPUT); //กำหนดให้ Loads เป้น OUTPUT
	}
	mySerial.begin(9600); //กำหนมความเร็วในการส่งข้อมูล
	for (int i=0;i<4;i++) //ทำซ้ำไปเรื่อยจนครบตามเงื่อนไข
	{
	digitalWrite(Loads[i], LOW); สั่งให้ loads เป็น LOW
	}
	}
	2.void loop() //การทำงานซ้ำไปเรื่อยๆ
	{
	if(mySerial.available() > 0) เช็คขอมูลในเงื่อนไขว่าเป็นจริงหรือไม่
	{
	state = mySerial.read(); อ่านค่าที่ได้รับ
	flag=0;
	}
	switch(state)
	{
	case '0':digitalWrite(Loads[0], HIGH); เมื่อกดสวิต 1 ให้ loads เป็น 1
	flag=1;
	break;
	case '1':digitalWrite(Loads[0], LOW); เมื่อกดสวิต 2 ให้ loads เป็น 0
	flag=1;
	break;
	case '2':digitalWrite(Loads[1], HIGH);
	flag=1;
	break;
	case '3':digitalWrite(Loads[1], LOW);
	flag=1;
	break;
	case '4':digitalWrite(Loads[2], HIGH);
	flag=1;
	break;
	case '5':digitalWrite(Loads[2], LOW);
	flag=1;
	break;
	case '6':digitalWrite(Loads[3], HIGH);
	flag=1;
	break;
	case '7':digitalWrite(Loads[3], LOW);
	flag=1;
	break;
	case '8':digitalWrite(Loads[0], LOW);
	digitalWrite(Loads[1], LOW); กำหนดให้สั่งเป็น LOW ทั้งหมด
	digitalWrite(Loads[2], LOW);
	digitalWrite(Loads[3], LOW);
	flag=1;
	break;
	}
	} จบการทำงานของโปรแกรม..

September 06, 2018

Overview by Steve Hoefer Nothing says "There's something valuable here!" than the sight of a lock. But what if the lock was invisible and the unlocking key could be transmitted through solid matter? No one would even know there was a lock, much less how to pick it.

That's what the Secret Knock Activated Drawer Lock does. It hides all of the lock mechanism away and can only be unlocked by something you know: a secret pattern of knocks.

A solenoid locks secures the drawer while a piezo buzzer listens for knocks. A Trinket compares the knock pattern to the stored secret knock and if they match the solenoid latch retracts and the drawer can be opened. Setting your own custom knock is as simple as holding down a button and tapping the new rhythm.

The project is relatively straight forward and you should be able to complete it in an afternoon. 

As always, read and understand this guide completely before starting the project. Parts & Tools by Steve Hoefer This project only r…
