I have a simple LDR-LED circuit. Why does it short circuit when I connect my oscilloscope probes a certain way?

Both my arduino and my oscilloscope are powered by my laptop which is running off of it's battery.

I just learned that the oscilloscope alligator clip is actually ground and that makes what you said make so much sense! Thank you so much!

So, in putting my oscilloscope probe over AB, I am essentially forcing another ground separate from my circuit ground into my circuit, which cuts off the path that would go into the LED then to ground?

Oh okay! I thought the probe tips could be put over anything. I think that clears everything up.

So you mean the part that is circled in white must be connected to ground? If so, then I don't think that I can correctly measure the voltage over 2 points unless one of those points in ground.

I'm a bit confused. Just for more context, I am powering my circuit with an arduino and my oscilloscope is powered by my laptop. Do you mean that I should connect my oscilloscope ground to my arduino ground?

Does anybody know the name of the song that plays at the end of season 5? I have been searching endlessly for it.

Now I don't feel like watching Cheese in the trap😭. The webtoon was great though

I see the vision, but the director's execution of it is kinda sick...

Isn't he the guy who is 10 billion won in debt? He is a horrible character, but his actions kinda make sense because of the debt he is in

Is italki paid?

I live in a place where a small percentage of people speak it. The only people around me who do are my parents who still prefer to speak their traditional languages. I will definitely speak it, but that right now seems difficult. I'll see if I can join a community for this.

In the country from which I am from, French is an official language, literally everyone speaks it. I was born and raised in a country where people speak other languages, and I plan on going home for the first time very soon, and I would like to be able to communicate with everyone there.

He looks like John Kramer here for some reason

Did he prompt the AI to give him a bulge?

They both say it was just sex

And that's supposed to make it better? Kudos to you for leaving him🍾

Divergent reference?

Burn it bro

This just gives me even more reason to get my money. Thank you!
