Aergia: Android controlled TV Remote(with Speech Recognition)

FeaturedContest WinnerContest Winner

Have you ever faced this situation while sitting on your favorite spot on the couch or recliner, comfortably watching your favorite TV program? You're snugly tucked under the blanket, the air conditioning is pleasantly cool, the sun outside is shining it's delicate warm golden rays on the closed window, the air (from the air vents) is refreshing and gravity seems infinite...... It's almost like nature doesn't want you to get off your couch.......

Then all of a sudden a horrible commercial pops up on the TV and you desire to switch the channel immediately. However, the TV remote which is located just beyond your arm's length seems to be many miles away and you do not have the energy nor the will power to reach for it. You then look with disappointment at your aging Android phone which is near you and hope that you could use it to control your TV. If you're like me, then you're faced with this situation quite often......... in fact EVERYDAY!

As a solution to this quite serious problem, I have devised 'Aergia' (named after the Greek goddess of laziness and sloth), a gadget which with the help of an Android phone can control my TV, set top box, stereo or any other device which uses an IR remote. Besides, this device can be built at a cost of just $20 and the skills required to build it are bare minimum (basic knowledge about electronics and the Arduino IDE).

So let's get lazing....... I mean building!

I need more details in the step 6,the points that RickD2 cited

I'm glad that my phone already comes with an IR Blaster (Something I didn't even realize existed until recently) So I can use it as a remote directly. But this is still a very cool project, keep up the good work!

can you please provide source code of your bluetooth control app? It will be very useful for me for another projects.

Hi, I'll pm you the app details

Me too

Jayvis: Could you post a more detailed step by step (preferably with pictures) on step 6:part 2 regarding the soldering of the 10 and 20 ohm resistors to the PCB board? I found that part confusing...have no prior experience with creating these types of circuits but I would love to learn how! Thanks for sharing your genius with us! :)

Jayvis Vineet Gonsalves (author)  RickD21 month ago

Thanks for pointing that out. I'll further elaborate that step to make it easier for everyone to understand.

This sure beats getting off the couch to fish our the remote from under the cushions!

cool project, congratulations. But, I am interested in your app, for a future project. There is the possibility to send me the source code?

Could this be used with an iphone

Although you can use an iphone in this project, you'll have to create a bluetooth remote app for your iphone.

Can this be built by a girl tha ?...
.

Yes, you too can build 'Aergia'! Just follow the steps in this instructable, and if you run into a roadblock while building this project, feel free to write a comment and I'll answer it.
