Hey guys, im here with a new question
im designing a plc with a 16f628A, and im here to see if i did something wrong
the thing is, ive seen some designs at internet and some of them have their inputs with a 10k resistor from 5v, and then they go to ground via the optoisolator
something like this:
and in my design, i have the inputs with a 5v input, and then trough a optoisolator and a 1k resistor
is there something wrong with my design?
this is by the way
