Product Description

The project is designed to use a TV remote as a cordless mouse for the computer. A conventional PC/laptop uses a mouse to operate and control all its applications. As a PC mouse is wired to the system, one has to sit near the PC to operate it.

This becomes very tedious when the PC is used for presentation purposes (when using a projector). In this proposed system TV remote can be used as a cordless mouse, and the user need not operate the PC sitting near it.

A typical TV remote sends coded infrared data that is read by an IR sensor interfaced to an 8051 family microcontroller. This data so received by the microcontroller sends it to the COM port of a PC through a level shifter IC. This IR code is traditionally RC5 code as followed by some manufacturers. Software named PC remote is used on the PC that recognizes data received from the microcontroller through the COM port and performs the required operation.

Designated numbers on the TV remote are used to perform up - down, right - left cursor movement. Features like left click and right click of the mouse can also be performed with of the TV remote.

Further this project can be enhanced using Bluetooth/ RF technology to overcome the traditional line of sight communication drawbacks of the infrared type.   

NOTE:

The project works only on operating systems having hyper terminal (E.g. Windows XP). The computer must have a RS232 serial port.

Get 100% Assured Successful Results

A simple and effective plan that assures you the best scores, a plan that gives you time to read, learn, practically experience the whole workings of your project and create a successful unit you can proudly showcase. And the best part is this… even if your own project unit malfunctions... you will still have a ready-made project unit for yourself, just in case there is a last minute issue that you or your teammates could not solve. Confused? Well let me explain.

Plan A: Create A Successful Project Model By Yourself

Plan B: Have A Expertly-Made & Quality-Tested Replica Of Your Project For Assured Results

So here’s how it works.

In my engineering days, we used to struggle replicating a PCB model from our text books with real tools. We had a tough time with the circuits and most of the time - they used to fail. So I wanted to solve this problem not just for myself but for all my fellow students like you. Young, energetic and knowledgeable youth who really want to learn but still cannot afford to fail with the project because it matters and the colleges rarely help us out productively.

So I want to give you a beautiful DIY model of the project that also includes:

  1. A Complete set of tools, circuit diagrams, tested PCD, zero board, audiovisuals and everything else you will need to execute your project to perfection.
  2. A ready-made unit of the project itself, so that you can actually see, test and learn in real-time and if by any chance you could not complete the unit by yourself - can submit this unit for an assured first-class score.

Sounds like a dream? Well, yes it is and here’s how you can benefit from this project not just in your final year but also help you with your interviews and in the future too.

"I live in Hyderabad, a place that is known for engineering colleges. Went with frnd and bought a set from Ameerpet(tht hs rdymade stuff like this) and it failed just b4 viva. Thats when we got this thx to a senior who is sorta like a geek.. and let me tell u.. Its one reason why me and my frnds got thru the final sem. Works great and is useful too later.. "

"A must-buy. It helped me practice in real time and learn how to make a project by looking at an actual workable unit. (fyi - you get a fully built unit and another full set of components to build another by yourself) so it was great value for us. We shared the costs by 3 (our team for the project) but i got to keep my unit as the other two kept the original. Showed it for my on-campus and got thru too becuase it not just looked neat and profesionally bt worked great later. (still have it in my room, now working with GE in Bangalore) "

"We have used it for our institution - it is available in lab and has been good for explaining various models in live during class. Strongly suggest every college dept to have it for labs as it is working well - even with regular use at lab for more than 1 year. Note:We got the unit complementarity before launch in 2014 and have later purchased few batches. The team behind it is professional and know what electronics students need and i am writing this review on their request on 13/05/2016"

Q&A

Q:  What is the distance supported by TV remote?

A:  The distance supported is about 10 feet

Q:  Can this system be used with any PC or laptop?

A:  Yes, this system can be used with a PC directly. But for a laptop, a USB to DB9 converter is used.

Q:  What is the function of level shifter Max232?

A:  Level shifter Max232 is used to shift logic level from TTL to RS232 and vice-versa

Q:  Can I use in Windows 7 or higher OS?

A:  This project has been tested with Windows XP only till date.

Q:  How can I use it with an USB?

A:  You require USB-to-DB9 converter to use it with a USB.

Q:  What is the family of microcontroller used?

A:  A microcontroller from 8051 family is used.

Q:  What is the formula for calculating smoothing capacitor value?

A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
