How to use 5V supply

i just got arduino for fun and trying to connect 5v supplies to my breadboard and my LED is not lighting up

With no other information, my first guess is that you are connecting things to the breadboard wrong. It's a very very common beginners mistake. Here's an article about how breadboards work. Read through this and check to make sure you aren't accidentally shorting out your power or LED.

Hope this helps!

Your problem is not unexpected, and your wiring may be the root cause. Since hardware is involved, it’s crucial to provide an accurate, annotated schematic of your circuit as it is currently wired. Please note that Fritzing diagrams are not considered proper schematics; they are wiring diagrams and are often not helpful for troubleshooting.

What to Include:

  1. Annotated Schematic: Show all connections, including power, ground, and power sources. This helps us understand how your circuit is set up and identify any potential issues.
  2. Technical Information Links: Provide links to technical documentation for each hardware device used in your setup. Avoid links to sales sites like Amazon, as they usually lack the necessary technical details. We need complete specifications to help you effectively.
  3. Additional Information Needed: If the above details are incorrect, more information is required. Tell us what hardware and software you are using, the format of any data (like map data), and how your system determines its position. For example, if your project involves a robot, describe how it navigates and what computers are involved.

Why This Matters:

We have no way of knowing the specifics of your setup unless you provide that information. Clear and detailed descriptions enable us to offer the most accurate help possible. Without these details, it’s difficult to diagnose and solve the issues you're experiencing.

  • Maybe it was inserted backwards.

  • In the future, please follow the Web Site’s posting guidelines.

  • 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.
