Use your TV remote to send SMS to any mobile

Very often while watching TV, we find it important to send message regarding any TV show or any news update. But as mobile is away from your approach and you are only having TV remote in your hand, you avoid sending it because of our lazy nature.

Well, now we don’t have to keep avoiding sending messages to our beloved one while watching TV because we can make our TV remote itself to send SMS to friend’s mobile. Idea is somewhat funky…But it’s possible.

Here is how we can do it.

Requirements:

• TV remote
• Arduino board Lego kit (as it has got inbuild open source library to access TV remote).
• LCD to displayed written message while typing
• GSM module (which actually sends your message to your beloved one’s mobile.

Showed above is the flow of algorithm.

I have used SONY remote to send messages. Because SONY/ PHILIPS remote library for RC5 encoding is available on net on this link: . Attach IRRemote library in arduino code.

IMP Note: We have to make receiving IR sensor circuit to receive RC5 encoded message from remote. Basically RC5 is encoder standard i.e. remote converts the data into RC5 format and sends it through IR transmitter. Now if we connect IR sensor with Arduino and decode that RC5 encoded stream then we can actually get the data sent by remote. You can use any remote for your convenience but keep it in mind that open source library should be available for that remote.

Now Arduino has pin 1 allocated for digital Serial Tx. So once we have received the data from remote, we can interpret that commands into AT serial commands of GSM module which are listed on this link and send it serially though pin1 of Arduino to GSM module. But to convert Tx pin1 to RS232 serial port we need to make a circuit which is in this link.

Now your remote is ready to work as sms sender. I have written an Arduino code to decode RC5 coded data and send it serially from TX pin of Arduino. If anyone interested to work on it I can send you arduino code for that.

Hope you have enjoyed reading it. For any queries drop me a mail and leave comment with your feedback.

Thanks for visiting blog. Keep looking lots of new ideas are waiting for your review. :)
