Hello and thanks always
Other than doing the projects I do (and in which I get so much help from you guys, always appreciate it) sometimes I have very basic questions. I would be grateful if someone can help me on this too.
They are very basic questions though.
In this occasion, I would like to ask about this situation
Say I have two ICs, or an IC and a component. One of the pins of part 1 is connected to one pin of part 2.
Part 1 transmit a 1 or a 0 uinidirectionally to part 2
My question is: How can I put a LED there, so that this indicates me when a 1 is being transmitted??
The parts I am using is a 3.3 V PIC for part 1 but the question is in general for a 5V PIC or any other component. Part 2 this time is a LCD, but again the question is in general
