and this is the chip that I was talking about last time. This basically sends information to a tr uh transistor here , which then uh sends the information to an L_E_D_ device here. If you flip the printed circuit board , and this is th the most important point here ,
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.
