  Construction:- 

1) Insert IC base into zero pcb.

2) Solder it. Learn How to solder.
3) Insert variable resistor and solder it.

4) Interface pin no.4 and pin no.8 to each side pin of variable resistor.

5) Interface pin no. 2 to front pin of variable resistor.

6) Insert IR receiver and solder it.

7) Insert 10k resistor and solder it. 


8) Interface negative end of  IR Receiver to one end of 10k resistor, and other end of receiver to one side pin of variable resistor as shown in circuit diagram.

9) Insert IR Transmitter and solder it.

10) Insert 100 ohm resistor and solder it.

11) Interface negative end of  IR Transmitter to one end of 100 ohm resistor, and other end of transmitter to IR Receiver.

12) Interface the other ends of resistors (10k ohm and 100 ohm) together, and interface it with another side pin of variable resistor.

                    Half part is completed.

13) Now Insert Buzzer, LED, and 220ohm resistor and solder it.

14) Interface negative of buzzer to negative of LED.

15) Interface one end of resistor 220 ohm to positive of led, and another end to positive of buzzer, and interface it to pin no.1 of IC.

16) Interface negative of buzzer to pin no.4.

17) Insert two terminal resistor and solder it.

18) Interface positive side of IR Transmitter to one pin of two terminal connector.

19) Interface Resistors side to another pin of two terminal connector.

20) Take a wire, interface pin no.3 to negative of IR sensor.

21) Connect battery connector.

22) Connect the battery, and rotate variable resistor to its full potential.

Now take any object in IR range and Buzzer will buzz and LED will glow.

IOT Internet Of Things- Every Thing You Need To Know About Internet Of Things

IOT- Every Thing You Need To Know About Internet Of Things:-

Technology have grown up so much high from what we have expected our future in past decade.
From doing thing manually to now doing thing by sitting on you couch, we have evolved.




Therefore something new also has evolved from past years and that term is knows as "IOT-Internet of Things".
















The term itself defines what is IOT.

But here is the simple definition:- To control anything fromanywhere, regardless of your surroundings like 'chair, fan, t.v., lights etc, to something which is far away from you using internet is known as Internet of Things.

                                                         or

To connect a physical thing like fan and lights to internet, and running/starting them using your mobile device is known as IOT-Internet of Things.


Sounds strange right? But yes that is what we achieved.



Now lets look at how it is done:-









The best example of IOT is "Home Automation".
