FLASHLIGHT FOR PHONE

Send

As you know, the flash of the phone can be used as a flashlight. But with prolonged use, it can burn out and fail, and it also spends a large amount of electricity, which is why the phone’s battery runs out quickly.
The advantages of my flashlight option:

Compact size.
Bright light (slightly inferior to the flash of the phone).
Low electro consumption.
Easy to manufacture.

For the manufacture we need:
1. LED (diameter 5 mm, voltage 3 volts, color white).
2. Resistor 100. Ohm.
3. Micro USB plug with housing.
From the tools: soldering iron and nippers.

Manufacturing process:

1. Approximately determine the length of the legs of the resistor and LED.
2. We love all the contacts.
3. We need to close pins 1 and 2 of the Micro USB jumper (as shown in the picture).
4. We attach the LED to the resistor (in this case, it does not matter to which contact, without observing the polarity).
5. Pin 3 is (+), and pin 1 (-) (as shown in the picture), solder the LED plus to the plus of the plug and minus to minus.
6. It remains to install micro USB in the case and close it.
Thanks for your attention!
