If you want to independently improve your computer with some fancy "tricks", the easiest way is to use LEDs for this - they are easy to use, cheap and do not require any special skills and tweaks. LED is able to decorate your workplace, give it additional lighting, and just cheer you up. To connect an LED, follow our step by step instructions.
Necessary
- 1. LEDs
- 2.soldering iron and everything you need to work with it
- 3.resistors that will reduce the voltage and current from the power supply
- 4.connectors required to connect LEDs to a computer
- 5.voltage tester
- 6.nippers to strip wires
- 7.shrink tubing
Instructions
Step 1
Before starting work, make sure that you have all the necessary tools and accessories for the job.
Step 2
Connecting to the 4-pin molex connector First let's see how to connect the LED to the 4-pin molex connector. This is a fairly common connector in a computer, so it is quite possible that your computer has one. This connector contains four pins: 1. +12 V (yellow wire)
2. + 5V (red wire)
3. Two Ground Pins (Black) Choose whether you want to connect the diodes to 12 or 5 volts. Purchase the connector or remove it from the old unnecessary device. Use a tester to check if the selected contacts match, determine where the diode has positive and where negative contacts.
Step 3
Strip the wires with wire cutters, solder the resistor to the positive contact of the connector. Cover the connection with heat shrink. Solder the positive pin of the LED to the second pin of the resistor. Cover the soldering area with heat shrink tubing. Take the negative pin of the LED and solder it to the ground pin of the connector.
Step 4
Connect the LED to power and check if it works.
Step 5
Connecting to a USB cable You can also connect the LED to a USB cable. There are two types of such cables, but they do not have a fundamental difference in the course of work, so find any unnecessary cable and get started. There are four contacts in the USB cable, two of which transmit data, one contact is "ground", and the other one transfers voltage … It is to him that you need to connect the LED. Use a tester to check the voltage and determine the positive and negative poles of the diode. Use wire cutters to strip the wires transmitting voltages. Solder the resistor to the positive contact, cover the solder with heat shrink. Connect the positive pin of the LED to the second pin of the resistor and close the soldering point. Solder the negative contact of the diode to the ground contact, cover the solder with heat shrink. Connect the USB cable to your computer and check if it works.
