How to reprogram a tv b gone?,,,,,, if it is possible

i would just like to know if it is possible to reprogram a tv be gone with an arduino uno so that it also works on projectors, if it is how do i do it, kinda new at this

I doubt you can reprogram a commercial TV-B-Gone (it contains a microcontroller, but it's probably OTP (one time program)), but you can certainly make your own.

Google for Arduino TV B Gone for tons of information - seems this is a popular thing to do.

ya it is one of the radioshack's make it and it comes with the 6 prong port to program it
