hi everyone,

I am making a remote controll project where i have all the main buttons of my stuff like my hifi and tv remotes on 1 controller. however I was wondering how i could find out the baudrate of the transimision signal. is this even possible. I do have an ir reciever and i can use the uart and logic functions on my pic kit. I have founds these tools great help so far
 
how can i find the modualation frequency and protocols my controller uses. one of the controllers i use is a slimline type and isnt poosible to take apart. does that mean i cant use it???

Find the maker of the remote, different makers have protocols that they prefer to use and they're generally well described. If you can not find out who the maker of your remote is for some reason you can use an oscilloscope and a IR photo diode to watch the output the remote sends when you hit a button. If you have a DSO it is even easier as you can capture the entire pulse and view it easily.
