Pin LED Digital Tube Making Tutorial: Light Up Your World.
LED digital tube is a common electronic component, which is widely used in various electronic products. With simple fabrication, we can make it into a plug-in LED digital tube for various display needs. This article will introduce you to how to make a pin LED digital tube, as well as related precautions.
First, the basics.
1.The structure of the LED digital tube: The LED digital tube is mainly composed of multiple LED lights, and each LED light has a positive and negative pole. Through the circuit connection, the display of numbers and letters can be formed.
2.Materials: You need to prepare LED digital tubes, plug-in power supplies, solder, rosin, solder knives, universal boards (or wires), insulating tapes and other materials.
Second, the production steps.
1.Prepare the universal board: Prepare the corresponding number of universal plates according to the number of digits of the digital tube to be made. If you don't have a universal board, you can use a wire instead.
2.Connect the power supply: Connect the pin power supply to the universal board, and make sure that the positive and negative poles of the power supply correspond to the correct polarity of the digital tube.
3.Soldering LED lights: Connect the LED lights in the LED digital tube according to the lines of the universal board. Make sure that the positive pole of each LED lamp is connected to the corresponding line of the universal board, and the negative pole is connected to the ground wire.
4.Test: After soldering, use a multimeter to check if the circuit is working properly. You can use a small bulb or LED light as a load to check if each LED light on the digital tube is on.
5.Insulation treatment: In order to ensure safety, after all circuit soldering is completed, use insulating tape to insulate the exposed wire ends and universal boards.
3. Precautions.
1.Do not use a regular soldering iron when soldering to avoid fire or electric shock accidents. Soldering is carried out using specialized soldering tools.
2.Be sure to wear gloves and a mask to protect your hands and eyes during the welding process.
3.When using the universal board, pay attention to the length and direction of the connecting wires to ensure the correctness of the circuit.
4.Make sure that the power supply is sufficient to drive the LED digital tube, and avoid using too high or too low a power supply to avoid damaging the components.
5.After completing the production, be sure to check the circuit for short circuits or leakage to ensure safety and reliability.
Fourth, application and expansion.
1.LED digital tubes can be applied to various occasions that require numeric and alphabetic displays, such as electronic clocks, remote controls, instrument panels, etc. According to your own needs, you can make LED digital tubes suitable for your own applications.
2.In addition to the basic numeric and alphabetic displays, more complex displays can be programmed and controlled. For example, it is possible to control the brightness, color, and other parameters of each LED lamp to create a more colorful display effect.
3.In the production process, you can also try to use different materials and methods, such as using SMD LED digital tubes, using single-chip microcomputer control, etc., to achieve a more flexible and practical effect.
In short, through the introduction of this article, I believe you have a certain understanding of how to make plug-in LED digital tubes. I hope that through your own efforts and practice, you can make a practical, beautiful and safe LED digital tube to light up your own world.
