In this guide, we will walk you through the process of building a USB-powered LED light. This fun and customizable DIY project can be a great addition to your workspace, bedside table, or even your camping gear. Let’s get started!

 

 

To begin, you will need to attach your LED light and resistor to the USB cable. Follow these steps:

Step 1: Insert the LED Light into the LED Holder
Start by inserting your LED light into the LED holder. This will help keep it secure.

Step 2: Connect the Positive Wire
Take the stripped portion of the red (positive) wire and twist it around the long (positive) end of the LED light. Make sure the connection is tight for a good electrical connection.

Step 3: Attach the LED Light to the Resistor
Next, connect the short (negative) end of the LED light to one end of the resistor using the same twisting method as in Step 2.

Step 4: Connect the Resistor to the Negative Wire
Finally, attach the other end of the resistor to the black (negative) wire using the same twisting method. After completing this step, your red wire, LED, resistor, and black wire should form a single loop, in other words, they should be in series with one another.

Tip: If you have heat shrink tube, now is the time to slip it over your USB cable for easier setup later.

 

FAQs
Q1: What is a USB-powered LED light, and what are its common uses?
