LED strips are a great way to add a lot of light and color to a project in a fun and cost-effective way. You’ll learn about the many sorts of strips and how to connect them to an Intel Edison using an Arduino breakout board in this Instructable.

To begin, solder the wires to the light strip. If you don’t buy a full 5-meter roll of LED strips at once, you’ll get a larger quantity of strips that have been cut off and don’t have the leads attached. Soldering is straightforward; all you have to do is make sure the wires are connected to the correct side of the ribbon. At either end, there will be a set of four contacts, but the two contacts in the middle of one end will be labeled “DI” and “CI,” while the two contacts in the middle of the other end will be marked “DO” and “CO.” The “I” side (short for “In”) is the one you desire.

Because the connections are brittle at this point, I recommend using heat shrink tubing or electrical tape to reinforce and insulate them.

The LED strips should then be connected to the Arduino and the power source. The “DI” and “CI” (Data In and Clock In) wires are connected to the Arduino’s two digital pins, while the other two are connected to the power supply and power source, as well as the Arduino’s common ground. Check out Adafruit’s great tutorial for a more in-depth look at wiring addressable LED strips.

Finally, you’ll need to submit the program to Arduino via your computer so that it can execute it using the LEDs. You’ll need the Arduino IDE (along with the Arduino USB driver) and a library to control the chip on the LED strip for this. This library is accessible for the individual strip I purchased.

I won’t go into detail about how Arduino works or how to utilize it because that will be covered in a subsequent guide. For the time being, I’d just like to point you that you can program the Arduino by writing a simple C program that specifies which LEDs should light up and when. It’s still being coded, so don’t be alarmed if that makes you nervous; nonetheless, controlling the LEDs is as simple as programming in C, and you can learn everything you need to know in just a few hours.

I added two buttons to the Arduino for my project and built a simple software that cycles through three modes (stationary light, slow “bounce,” and carnival mode) and various different color selections with the second button. I got some ordinary 3M double-sided mounting tape and applied it to the Arduino and LED strips to mount the backlight to the TV. I put the whole thing to the back of the TV, and now any movie or carnival can generate lovely mood lighting.

On Sunday morning at the Beijing Business Hall, I listened to a class by academician Jiang Fengyi, “An Introduction to LED Lighting”. Although I have known Jiang for decades and have listened to his lectures many times, this time was different, as he spoke for an hour and forty minutes in one breath, his throat was hoarse, and he was still answering questions and solving problems on the spot. The designers at the scene were very responsive and strong in learning, and there was active interaction on and off the stage.

Academician Jiang is modest as always, he is the top scientist in the LED industry, the opening of the lecture even said shallow talk. This really makes me ashamed, I often lavishly talk about what trends and directions when I speak.

Jiang academician this time about the development of silicon-based LED from 0 to 1 breakthrough, despite the difficulties, he still knows the difficulties. In the international many experts feel hopeless, he led the team still insist on overcoming difficulties. From the success of silicon-based blue light to silicon-based yellow light, green light, micro LED’s red light, etc., the same as the world’s forefront.

As a matter of fact, Jiang Yuan has already made a name for himself, promoted to the university vice president, the Chinese Academy of Sciences, can completely rest. But he did not, for scientific research is still sleepless at night and even often insomnia. He still fights in the front line, fighting in front of the “furnace”. He said that the U.S. government has included “Nanchang University” in the sanctions list, I have to scramble to do original innovation, starting from homemade equipment, so as to establish a leading position from the source, once successful, outside entrants are insurmountable.

Nobel laureate Mr. Shuji Nakamura, confirmed by their tests, the silicon-based yellow and green light of the JiangYuan team, confirmed to be unique and leading in the international, and personally wrote a letter recommending JiangYuan to receive the “Global Semiconductor Lighting Outstanding Contribution Award”. In this regard, the Jiang Institute of honor as a spur and incentive did not slow down the pace of progress. He believes that the technological innovation of LED is the sea of stars, worthy of continuous exploration. For example, golden yellow light, pure LED light, LED optical communication, and so on.

China’s LED from following to run, until some areas we have been in the lead, which is a rare historical opportunity, but also the stage results of the struggle of the whole industry in the past two decades.

LED not only stops at lighting but also beyond lighting, there are unknown “frontiers” to be explored, deep ultraviolet UVC LED, intelligent dimming, plant light, health lighting, etc. LED future unlimited possibilities, will make people’s hearts surging. You think, Jiang academician so successful, but also so hard work, we have what reason to slacken it?
