Mm-hmm.
uh  everything else is kind of  Okay , so if you flip the circuit board , this is what it looks like. So you see for example a particular button attaches to a particular place on the P_C_B_ and uh
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 ,
