With the development of various digital products, USB plugs are seen everywhere. The plugs of various chargers and data cables are all USB, which is convenient for us. Let's make a utility tool by using the USB plug which removed from the data cable.
First, I soldered a resistor and a wire for powering the USB plug.
Next, put it in to the half plastic case(made by plug), trim the pins of LED and solder the LED to the two sides of the USB.
Then, install another half plastic case and a mini USB night light is ready.
If it is interesting, you may also try to make such an LED night light with a USB plug and share it with your friends.
