Debugging Circuits
So how do you debug a circuit? Start with the easy stuff:
Is it plugged in?
Did it blow a fuse?
Is it drawing power and if so, how much?
If it’s digital, did you turn it off and turn it on to reset the microprocessor?
Even better, did you disconnect the power entirely? Some processors have keep alive circuits so they’re really always on.
Enough for now. We’ll start with appetizers before we get to the main course.
