Fantastic price for a fantastic LED strip. It's so much fun programming them to display a beautiful light show! It's extremely easy to control with Arduino, but you need to make sure you set it up correctly to avoid damaging the strip. Here's what you need: 1) Since each LED draws between 20 and 60 milliamps and there are 30 of them on this strip, you'll need to supply a separate 5V / 2A power supply to drive it since the Arduino can only supply 500mA through its 5V pin 2) You should add a 1000uF capacitor across the +/- terminals of the power supply to prevent an onrush of current which could destroy the entire strip 3) You should add a 470Ω resistor between the Arduino's data pin and the strip's data pin to prevent spikes on the data line that might destroy the first pixel in the strip Follow those precautions and you'll have a great time with this inexpensive, fun RGB LED strip :)
parece de boa qualidade, bem embalado
muito bom, fácil de programar usando arduino
muito brilhante e tem cores bonitas. Há muitos links do youtube como usar isso. Basta procurar "WS2812". Os LEDs podem ser tratados separadamente. Há um monte de bibliotecas que podem lidar com esse chip.
conforme aux attentes
I forgot to order the remote, so I’ll wait to do the tests.
Got my package before the expected delivery date. tahnk you very much for the responses to my concerns.
Need to try these asap. All seems to be there. Thank you
Works perfect. Pretty and bright colours. With adhesive back side. Maybe waterproof. Connectors on both sides so you can connect more stripes in series.
Todo perfecto
