Ir Remote Control





Introduction: Ir Remote Control

About: I am a student of BSCS but I'm interested in electronics that's why I would like to think about innovative ideas and try to build my ideas into reality and i also interested in making a robots. email id: deg...

Hello! guys today i'm gonna show you how to make your own ir remote control with the help of this you can control your any home appliances. So let's get started

Step 1: Circuit Diagam and Components

Here it is the circuit diagram which we can build it with the help of this diagram. This diagram is available on google images i just saved it and make my own ir chip with this diagram.


IC: cd4017 with base and TSOP 1738 (ir receiver)

Resistors: 4.7k x 2, 1k, 100 ohms,100k

Transistors: bc557 and bc547

5volt relay

Diodes: 1n4148 (zener)

Led: red or any other

Capacitors: 10uf

Step 2: Placing Components

put the components on vero board at right place according to diagram

Step 3: Soldering

i just make a solder track because it's much better than other type of soldering.

Step 4:

and finally its build by me its very easy.

I hope you guys like it.

    I'm new to this stuff i made a Ir remot project were you are soposed to turn led on and off with remot but I don't know how to find a code To open and verify it with on audrino

    i mean metal ofcourse sry for the typing errors:) :) :) :)

    can anyone please help me
    when i did the circuit on the breadboard everything was working just fine bat when i did it on the pcb it isnt working. It isnt detecting thw remote but the circuit activates the relay when i insert a meral or smthng in between the transistor bc 547 lead .Do can anyone please help me out

    Thanks for sharing thia project but I have a ton of questions

    firstly, how do you program that thing so it works the way you want, for example how do I program it so I can increase and decrease fan speed

    why not sunilb6. Basically its infra red (IR) remote control with the help of this you can easily on/off your electronic device. You just simply build this and connect your any device according to relay's amp like printer, scanner, PC etc and then simply hit the power button through remote your device will be on and vice versa.
