How to make a Remote control for any appliance.


                                                   Here is a very interesting project by which you can control any electrical appliance in your home by using remote control of your TV, DVD Player, VCR,or even a IR signal from your mobile phone. The circuit is all simple .I found this circuit in an electronics amateur magazine EFY and after that, many circuits with far more  voltage stability were released by EFY itself.

 By this project you can understand all the possibilities of infra red which is very common nowadays.However the circuit which shown here is the latest model which is developed by an anonymous user but it is the best of all IR remote switch circuits.

This is the prototype which i developed with some modifications 

  • Added 230v ac to 12 v DC and 




  • Used a TK 1738 instead of the 1838




  • Added a potentiometer meter and hence were able to control the sensitivity of the sensor 


Although the building of the above circuit is so simple but still i recommend of assembling the components on a bread board instead of soldering.You can use this circuit an many other ways such as a HI FI security system.
            For that you we must have a continuous IR source on the sensor, and if the IR waves are disturbed., The relay will be cut on and the load will get supply you can use a Alarm as the load and can turn your IR switch to a security system.  

This IR switch has many other practical applications.
Now let us get into some of the drawbacks of the circuit,the sensor which we used here is highly sensitive even if we added potentiometer to it. Thus in order to make the sensor respond for only the correct amount of signal,we must rely on some other method.Like replacing the sensor with preassembled IR sensors and remotes which are available in the market .
                             The use of such sensors will make our circuit more elegant as it can be controlled from its own remote.There are many other add ons for this project further modifications are welcomed.
