Adding Remote Control To A TV

[dtengineering]

Thank you for mentioning that you are using a Tauntek IR receiver. The more information you provide, the better we can answer your questions. In this case it would have been very helpful if you could have provided the exact Tauntek model you are using and a link to their website embedded in your question. Sure we can Google it ourselves, but if you provide direct links we can spend more time answering your question and less time looking up what parts you might be using. Telling us more about what motors you have available... servos, VEX motors, stepper motors from old hard drives, etc. can also help us make useful responses.

Looking at a schematic for one of the Tauntek IR recivers (http://www.tauntek.com/TinyIR-four-c...-schematic.pdf) it appears that the outputs come directly off a PIC microcontroller.

PICs are typicaly able to source/sink about 25mA per pin. Although that is enough to drive an LED, you would have a hard time running any motor off of that! You have a number of methods available to do this, including simply hooking up a transistor to amplify your signal from the PIC. If you want a small DC motor to go both forwards and backwards, you will need an H-bridge circuit, like this one http://library.solarbotics.net/circu...er_tilden.html or an H-bridge chip like the L293DNE. If you are using a stepper or servo motor you may need to build a custom interface, as both those devices expect a modulated signal.

So in a word... NO... don't hook a motor up directly to the Tauntek. At best nothing will happen, at worst, you'll fry your PIC chip. But DO experiment with some of the circuits here, take some time to google "H-Bridge" and "motor speed control", and other related topics and feel free to ask more questions here.
