Ótimo Projeto. Ganhou mais um inscrito.

[@manjeetsondh]

So nice and simply explained. Good job.

[@michaelmcpeters8098]

The only change I would recommend would be to evenly distribute the 5v/Gnd across the matrix.. (5v in one side, Gnd the other) it'll make sure the display is evenly lit across the strips.

For connecting the terminals using the Red Yellow Black wires, cut the ends at an angle like 60 or 75 degrees for easiness. Thank you for the videos my friend.

[@kanniahnaiduvenkatesh7094]

[@suneetasandeep]

The only small problem with these strips for making such display is the joint where two led strips is joined by manufacture. These joint normally misaligned the entrie matrix. For this de-soldering and re doing is required in order to align the same

Nice vídeo. Question: what's the biggest área (number x number) of leds I can do with same components, arduino nano and HC 05 module, 5 v?

[@agr00m]

Theoretically infinite given an adequate power supply. The bottleneck would eventually be the data packet size for very large arrays vs the desired refresh rate. I think the WS2812b only has a refresh rate of 400Hz, so you'd probably max out pretty quick for large scrolling text displays. Using something like the WS2813, with a 2000Hz refresh rate, would be better for a large display. But to answer your question, you'd have to calculate the baud rate for n LEDs, then see if that results in an overall refresh rate of 26hz or higher (lower than that the movement starts to look choppy).

[@knightsun2920]

The speed and data baud rate might be a problem, also you will likely need to remap all the LED's. There's only one data channel and it has to loop around all strands. This one by Josh Levine only has 7 strips in parallel but is nearly limitless with proper power inputs every so often. You have 2000 characters for a message as the message is stored in S-RAM. kzbin.info/www/bejne/oV62ioCGhJ1gnJo
