The ws2811 rgb led controller which we are making today also works on dc 5v.
Pixel led controller circuit diagram pdf.
In this circuit we will connect three 5mm white leds is series with the same 12v supply.
Led scrolling display circuit and working.
A sample circuit diagram is shown below.
The following image shows the circuit diagram of the leds in series.

Transmission limit of the pixel only limited signal transmission speed.
The first part has a power supply and controller circuit as shown in fig.
The power supply circuit is built around a step down transformer bridge rectifier and 5v regulator.
20 ma each for red green and blue.
The control circuit is integrated in the led above more simple circuit small volume easy installation.
The circuit diagram is divided here into two parts.

The rgb led strips i have bought have a male port and a female port.

Circuit diagram of leds in series.
Let us assume you are using a 5 led rbg strip neo pixel with arduino and then in that case the leds can be directly powered by the 5v pin of arduino since they can source upto 500ma.
The led has a low driving voltage environmental protection and energy saving high brightness scattering angle good consistency low power long life and so on.
This method can be used when you are using more than 2048 leds 3 wire ttl common power supply 5v is used for the controllers and the pixel led strings here are the connection between each component this is a example if two controller network you can connect more than two controllers like this way with two controllers connected this way you can control up to 4096 pixel leds.
The display unit is in the second part as shown in fig.
Circuit 2 of simple led circuits leds in series the next circuit in the simple led circuits project is connecting leds in series.
The led pixels are spaced along a strand of ribbon cable with about 3 inches 75mm between pixels.
Both types use an 8mm diffused rgb led 12mm refers to the size of the mounting hole for installation diffused pixels mix colors nicer.
The male port is used for sending the data signal from the controller to the leds.
Keep in mind that these leds are very sensitive in nature and hence have to be protected from voltage spikes and esds.
