Hello, another newbie question.
My son and I have completed the soldering. Thanks to the help from this forum, I think we have everything connected properly. I also have my shinny new multimeter, and we are now on the step about "smoke testing." I did the continuity testing and I think everything is OK. (it beeps if both probes are on ground, but no beep if one probe is on ground and the other on a power bus). I think that is good from what I understand.
So, in Admin's tutorial, after the continuity test, he says "If you put the multi-meter on the resistance setting, make sure all non-connected pins have at least 5 kohm resistance or you may have power issues."
Can someone elaborate on how to do this test? Does this means pins that are not connected to anything?
Finally, he talks about a 'smoke test': "This is when you power up your circuit with a power supply. Plug your circuit in, start the voltage at 1V and work your way up slowly to 6.5V."
Again, I am not sure how to do this. How do I start the voltage at 1V? Is this the setting on my multimeter? Or an I supposed to be able to limit the amount of power going into the circuit? If the later, how do I do that? We are using the 9v and 4AA battery combination. As far as I know, I cannot limit the power of those sources.
Again, my apologies for the simplistic questions. I appreciate any assistance. Thanks so much.
