LED strips
LED strips are flexible circuit boards with full color LEDs soldered on them. There are two basic types of LED strip: the "analog" and "digital" kinds. Analog strips have all the LEDs connected in parallel. So, they act as one huge tri-color LED. In case of an analog LED strip, we can't set the color/brightness of each LED. So, they are easy to use and inexpensive. Digital LED strips work in a different way. To use the LED, we have to send digital code corresponding to each LED in the case of a digital LED strip. As they provide more modularity, they are quite expensive. Also, digital LED strips are difficult to use compared to analog LED strips:
Internally, RGB LEDs are connected to each other in parallel. One section of the strip contains all three LEDs, connected in parallel. A complete LED strip is made up of a number of parallel RGB LEDs connected in series. Connection in one block/section is as shown in the following figure:
As one section contains multiple LEDs, it requires...
