![]() ![]() ![]() ![]() Its 3 analog outputs are connected with R, G, and B terminals and change all three LEDs’ brightness. To generate different colors in RGB LED, we are going to vary the brightness of RED, GREEN, and BLUE LEDs from 0 to 100%Īnd we know Arduino can easily vary the brightness of LED! So that’s it……Īrduino has an analog output (PWM output) that will vary LED brightness. To generate different colors from RGB LED, we have to vary the intensity (brightness) of RED/GREEN/BLUE LED. Here, in our case – the color amount is color intensity – which means the brightness of RED/GREEN/BLUE LED. ![]() So next question is how to vary the amount of these three colors? (It is possible in painting as we can change their amount or dilute them, but here it is not so!) To generate other colors, we have to vary the amount of RED, GREEN, and BLUE color because we know the mixing of these three basic colors in different amounts will generate all colors. If we turn on two LEDs together, then we have 3 more colors.Īnd if we turn ON all 3 LEDs together, then? Yes, it’s a white color.īut still, 3 + 3 + 1 = 7 colours! What about more colors like PINK, ORANGE, SKYBLUE, LIGHTGREEN, etc.? So here is the logic to generate other colors. What about other colors? How can we get (generate) all colors from RGB LED? Now you all might be thinking that there are only 3 LEDs in this, and we can have only 3 colors RED, GREEN, and BLUE. While in common anode SMD RGB LED, common terminal is connected with +Ve supply and R, G or B terminal has to be connected to ground. It is understood that to turn on any LED in common cathode type RGB SMD LED, we have to apply +Ve supply to R, B, or G terminal, and the common terminal is connected to the ground. Please have a look at the figure given below. This common terminal can be either anode or cathode, and based on it, there are two types of such LEDs (1) common cathode and (2) common anode. Three terminals are for RED (2), GREEN (4), and BLUE (6) LEDs, while the other 3 terminals are common terminals. Before directly jumping to the LED strip, first, let us understand the single-cell – the building block of the strip – and that is one RGB LED SMD typeĪs you can see in the above figure, a single RGB SMD LED is a combination of 3 tiny individual RED, GREEN, and BLUE LEDs.You can do all these and play with such RGB strips using ARDUINO, and it’s very easy and simple. What if I say all these you can do with our ARDUINO? Sounds interesting…….?!?!!!? So do you want to build something like this? Like a multicolor LED chaser, fading, and other animation effects using multicolor LEDs? I bet you all might have seen somewhere the “ jaw opening” multicolor led chasing, fading, and animation effect.Īll these are possible using such RGB LED strips. These RGB LED strips can generate almost all the colors and their shades using different combinations of RED – GREEN – BLUE.Įven they can generate different “ eye-catching” illuminating effects like multicolor, rainbow, LED chaser, fading, etc. So such strips have 4 connections (1) +12 V (2) R – for Red LED (3) G – for Green LED (4) B – for Blue LED RGB strip with separate R, G, B inputs: these types of RGB strips have three separate inputs for Red, Green, and Blue colors with one more common input as +12V.RGB strip with addressable RGB LEDs: these types of RGB strips have only three wires for connections (1) +12 V (2) Gnd and (3) DI-Data input.There are two types of RGB LED strips available in the market: The decoration using these RGB LED strips serves as “ cheery on a cake” for every occasion or festival. Even modern houses, luxurious flats, restaurants, and hotels use RGB LED strips for illumination and decoration. They are also used for decoration in festivals like DIWALI, CHRISTMAS, etc. They are used in different functions like birthday celebrations, marriage, reception, parties, etc. RGB LED strips are nowadays used everywhere in decorative lighting. ![]()

Whether your wedding rite is secular or religious, this ceremony lends itself to a musical opportunity. However, I am not aware of any Vatican prohibition of this “add-on,” and most parishes allow it, should the couple desire it.” “The lighting of a unity candle is not a part of the official Catholic wedding ceremony - i.e., it is not included in the Vatican-approved rite of marriage. ![]() The Catholic Church is a stickler when it comes to wedding liturgies, but most allow the unity candle ceremony. You’ll see the ceremony take place in both religious and secular ceremonies. Some trace the origin of the tradition to an early 1980s television soap opera. Following the exchange of vows and rings, the bride and groom light a larger, “unity,” candle with two smaller tapers, symbolizing the unity of two lives and two families. ![]() The unity candle ceremony is a late 20th century American innovation. ![]() ![]() ![]() The specific factors and conditions that allow pluripotent stem cells to remain undifferentiated are of great interest to scientists. Such information may also enable scientists to grow stem cells more efficiently in the laboratory. non-stem) is regulated during normal embryonic development and post-natally, or misregulated as during aging, or even in the development of cancer. What controls the balance between these types of divisions to maintain stem cells at an appropriate level within a given tissue is not yet well known.ĭiscovering the mechanism behind self-renewal may make it possible to understand how cell fate (stem vs. When a stem cell divides, the resulting two daughter cells may be: 1) both stem cells, 2) a stem cell and a more differentiated cell, or 3) both more differentiated cells. ![]() Unlike muscle cells, blood cells, or nerve cells-which do not normally replicate- stem cells may replicate many times. Stem cells have the ability to self-renew. Stem cells have unique abilities to self-renew and to recreate functional tissues. What are the unique properties of all stem cells? These stem cells may remain quiescent (non-dividing) for long periods of time until they are activated by a normal need for more cells to maintain and repair tissues. Adult stem cells have been identified in many organs and tissues and are generally associated with specific anatomical locations. Throughout the life of the organism, populations of adult stem cells serve as an internal repair system that generates replacements for cells that are lost through normal wear and tear, injury, or disease. Those reprogramed stem cells are called induced pluripotent stem cells (iPSCs). In 2006, researchers identified conditions that would allow some mature human adult cells to be reprogrammed into an embryonic stem cell-like state. Previous work with mouse embryos led to the development of a method in 1998 to derive stem cells from the inner cell mass of preimplantation human embryos and to grow human embryonic stem cells (hESCs) in the laboratory. The inner cell mass will ultimately develop into the specialized cell types, tissues, and organs of the entire body of the organism. The trophectodermal cells contribute to the placenta. Adult stem cells are found in a tissue or organ and can differentiate to yield the specialized cell types of that tissue or organ.Įarly mammalian embryos at the blastocyst stage contain two types of cells – cells of the inner cell mass, and cells of the trophectoderm. Pluripotent stem cells have the ability to differentiate into all of the cells of the adult body. There are several main categories: the “pluripotent” stem cells (embryonic stem cells and induced pluripotent stem cells) and nonembryonic or somatic stem cells (commonly called “adult” stem cells). ![]() Researchers study many different types of stem cells. They can develop into many different cell types in the body during early life and growth. Stem cells have the remarkable potential to renew themselves.

In this review, we will discuss how iPSC research will further contribute to human health in the coming era of precision medicine. More recently, iPSCs have been shown to validate effects of disease and treatment-related single nucleotide polymorphisms identified through genome wide association analysis. It has been shown possible to partially recapitulate disease phenotypes, even with late onset and polygenic diseases. Pioneering studies have shown that iPSCs derived from a variety of monogenic diseases can faithfully recapitulate disease phenotypes in vitro when differentiated into disease-relevant cell types. Breakthroughs in genome editing technologies and continuous improvement in iPSC differentiation techniques are particularly making this research direction more realistic and practical. Human induced pluripotent stem cell (iPSC) technologies are emerging as a promising strategy to fill the knowledge gaps between genetic association studies and underlying molecular mechanisms. It is still challenging, however, to understand how such genetic variations cause the phenotypic alterations in pathobiologies and treatment response. Such information is now expected to help evaluate individual health risks, design personalized health plans and treat patients with precision. Recent advances in DNA sequencing technologies are revealing how human genetic variations associate with differential health risks, disease susceptibilities, and drug responses. ![]() |
