First simple project using arduino won't work

Using Arduino Project Guidance
1

This is driving me batty so here I am hopefully someone can assist. I have an old Vilros starter kit and was going through some of the simple exercises using their coding. Suddenly nothing worked so went back to the first exercise consisting of 1 led light, 1 resistor, and the 5 volt wire, and negative ground. The coding up loaded with no issues. I have switched out the Uno with another one, as well as the breadboard, and the wires. Everything with no results. Keeping in mind it worked (the LED lit up) the first time but refuses to work no matter what I try. I have triple checked every item placement, so have no idea. I have watched the Uno while uploading and it definitely uploaded. Thoughts?

Always show us a good schematic of your proposed circuit.

Show us good images of your ‘actual’ wiring. Give links to components.

In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.

Use the < CODE / > icon from the ‘posting menu’ to attach the copied sketch.

I suspect your battery pack is insufficient. Show us what you have.

For reference:

The 72 page User Guide... Project 1 on Page 19.

The Code for 12 circuits...

I used the laptop as the power source. I went through the first three projects and thereafter none of the other projects worked and so I went back to project one in the booklet and have not been able to get it to work. I tried to attach a photo from my phone and tried multiple times to forward to my desktop with no luck. I don't understand if it worked once and is set up the same and the code got uploaded what the issue is.

If you are referring to Project #1, you did not set it up the same. For the circuit to work:

  1. The power source must be adequate (see page 20 of your user manual for connecting power)
  2. The LED must be correctly oriented (see page 20 for correct Anode and Cathode polarity)
  3. The code works, unless you tried to edit it.

There is never a time when "it used to work" is meaningful. Human interaction with everything is the cause of 100% of errors. Electricity works on physics, which is 100% correct.
