Making LED lighting

Thanks to such a simple invention as LED lighting, you can decorate various things and objects with bright lights. For example, casual shoes, roller or hockey skates, etc.

In order to backlight, we need a soldering iron with solder and flux, a 12V or 8V battery (the higher the voltage, the brighter our backlight will shine), an LED strip, several wires and a toggle switch.

A large number of LED strips are now produced, in our case we use a waterproof strip. This tape is attached very securely thanks to the adhesive surface.

It is best to take flexible wires so that they can be bent without the risk of breaking them. Both copper and aluminum will do. The cross-section of the wires is selected based on the amount of current that will flow through them. And since ours LEDs consume very little current, then the minimum cross-section is suitable. However, for high-quality soldering, the wires must be tinned, and the insulation of wires that are too thin will melt very much, so it is better not to use any strings at all.

To conveniently turn the backlight on and off, any compact switch is suitable; in our case, we use a 3-pin toggle switch. Toggle switches are also selected based on current, but in our case, I repeat, it is very small.

Let's move on directly to the soldering process. The most difficult part is the process of soldering the wires to the battery. In order to solder them securely and firmly, we first clean the metal contacts on the plus and minus with fine sandpaper or a regular knife. After this, we solder the wires to the plus and minus on the battery, having previously tinned them.

After this, you need to do the same procedure with the toggle switch. We also clean the contacts a little and solder the wires to them, taking one wire from the negative side of the battery. As we can see, the circuit is almost ready, only the LED strip is missing.

The LED strip has 2 contacts: +12V and GND. We take the wire from the positive side of the battery and solder it to the +12V contact on the LED strip. We solder the remaining free wiring from the toggle switch contact to the GND contact on the LED strip. In the photo below I can imagine what we should get.
