Yeah.
on pressing this button I  a circuit completes , the information goes to the chip , which is somewhere here and the chip that tra then translates the code into an infra infrared radiation , which goes goes out through there.  So uh the important point that I read over the website was uh that the configurations of these printed circuit circuit boards uh are quite cheap to make , you can ge get them printed as you want to ,
Mm-hmm.
so w we can have a configuration um irrespective of the cost , the way we want to have. Right ? So that's the important point here ,
