Designing a Remote Control: Beginner's Guide

Click For Summary

Discussion Overview

The discussion revolves around the design and programming of remote controls, focusing on both creating a remote from scratch and reprogramming existing ones. Participants explore various technical aspects, potential applications, and tools available for this purpose.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the process of designing a remote control, seeking foundational information.
  • Another participant mentions that most infrared (IR) remotes operate at a carrier frequency of about 40kHz, modulated with UART output, and suggests using a computer's COM port for modulation.
  • A question is raised regarding whether the design involves reprogramming an existing remote or creating a new one from scratch.
  • One participant suggests using a handheld device with an infrared port to program remotes for specific devices, noting the availability of software for this purpose.
  • Another participant shares their intention to create a general-purpose remote for various devices, indicating they have visual designs prepared.
  • A further inquiry is made about finding reprogramming software and the feasibility of creating a universal remote that can operate multiple TV brands, such as Toshiba, LG, Samsung, Sony, and Hitachi.

Areas of Agreement / Disagreement

Participants express various approaches and ideas regarding remote control design, but there is no consensus on the best method or specific tools to use. Multiple competing views remain on the topic.

Contextual Notes

Participants mention specific technical details, such as carrier frequencies and data bit configurations, but do not resolve the implications of these details for practical applications. There are also unresolved questions about the compatibility of remotes with different brands of devices.

Who May Find This Useful

Individuals interested in electronics design, programming, or those looking to create or modify remote controls for various devices may find this discussion beneficial.

Has anyone here happened to design a remote control...
I am just into it...so i am looking for information to understand how can we go about doing it..
 
Computer science news on Phys.org
Most (not all) IR remote output is a 40khz(about) carrier modulated with the output of a UART.
You could possibly use your computers com port to modulate the carrier if you can adjust the output word size large enough.
IIRC remotes use 10 or 12 data bits to the normal computer setting of 8 bits.
 
sorry for interruption, by designing a remote control, do you mean, reprogramm a remote or create your own from scratch?
 
If you have a Handheld, such as a pocket PC, then you can use its infrared port to program a remote control, for a TV for example. There are programs available for download that do this, don't know of any open source ones though. My Dell Axim has an infrared port.
 
we(i and my friend) are actually trying to make it for general purpose..like for devices like tubelight,fan,etc.etc.

i have actually prepared images what it would look like
 
where can i find the remote controller reprogramming programs heartless?
what ifi want to do ,for ex:a remote controller for a certain tv brand,say a toshiba tv remote works with other brands?such as(lg,samsung,sony,hitachi,etc),i want to make the one use remote to be more wide use for many kinds of tvs,how can i do this?
thanks in advance_:)
