Hi! During this pandemic with the lockdown, we will teach you how to make things with Arduino! If you have a small electronics kit that you've haven't used in years or months, and you want to learn arduino, then here are quick guides!
You wouldn't need any software, because we will use our Arduino for power.
But you will need the following items:
1: An Arduino UNO R3
2: Jumper wires
3: A serial cable or 9-volt battery adapter with battery
4: An LED
5: Breadboard (Medium or Large)
Start by connecting a red wire to 5V and a blue one to GND.
Hint:(5V and GND is in the pin headers labeled "POWER")
Connect these wires to your small breadboard. If you have a big one, put connect them to the power buses with lines colored red and blue.
Next, get your LED but make sure it works. Put the long lead, the "cathode" on the row where the red wire is. Place the short lead "anode" into the 3rd row, not on the GND row. Put a wire on the row the anode was, and place another wire on the GND row. Once you do that, connect the two wires to a spoon or a fork and the LED should turn on!
So you are teaching people to light an LED without any current limiting resistor. That is a bad thing to try and teach people. And I would have thought anti educational.
It means you were posting the same garbage on two different subject forums (or twice on the same) and thereby potentially wasting more people's time attempting to counter your misinformation.

If you have something to share, rather than a question, it belongs in the "Showcase" forum.
Thanks for adding a positive comment, rather than those garbage people... Adding comments that are mean. I thought that this website is supposed to be nice.
You're not going to get nice when you suggest connecting an LED across power & Gnd with no resistor:
"Place the short lead "anode" into the 3rd row, not on the GND row. Put a wire on the row the anode was, and place another wire on the GND row. Once you do that, connect the two wires to a spoon or a fork and the LED should turn on!"
The LED will fail, and likely fail as a short circuit (vs an open circuit) causing further damage.

So now those who didn't like WASTING TIME on your stupid joke are garbage people?
Maybe it's not just the joke that's "challenged" or a waste of time.
It has recently been brought to my attention that the OP could best be described as being of tender years (Hey! I never had a chewy one, but a cliché's a cliché).
Maybe we should tone-down the criticism.
(I genuinely thought the first post was a satire. I remember that Action Man (GI Joe) had a "mine detector" that operated on a similar principle, but at the time (about 50 years ago) LEDs were exotic and expensive, so used a tiny light bulb. Light bulbs don't need a current-limiting resistor)
