Okay.
We will discuss it afterwards. Oh , this is nothing. This is just my notes on what to use. And uh my personal preference is yes , I would like also preferably to use R_W_ circuit , but from the point of view uh of the design and price , I would stick to I_R_s. That's my opinion. Uh I mean if infra-red uh circuit not not the radio frequency.
Why ? Because it's simpler ?
Because because the the range where you can use it is fair.
