Tim writes: During the last months, a new WS2812 alternative appeared on the market: The SK6812. I finally managed to get my hands on some of them to take a closer look. In most aspects these devices are basically clones of the WS2812. What is interesting however, is that the manufacturer came up with a […]
Dmitry Grinberg writes, “Lighting a room is always a complicated task. This is especially true if you’re an engineer. You see, we all love blinking lights, RGB LEDs, really any combination of those things. When it came time to figure out the ligting situation for my room, I immediately knew that lots of LEDs would […]
Amir Avni made a graphic equalizer display using ESP8266-12, MSGEQ7 and WS2812: Finally, I’ve created a this project: An equalizer display controlled by ESP8266 with the NodeMCU firmware, where the equalizer colors are controlled via WiFi Project info at whatimadetoday site. Check out the video after the break.
cpldcpu writes: I contrast to the very timing-sensitive one-wire protocol of the WS2812, the APA102 uses a standard two wire SPI protocol – one clock line and one data line. Each LED has two inputs and two outputs which can be daisy chained. At the first sight this may seem wasteful, but it has the […]
Bogdan of Electro Bob wrote an article on using the WS2812 level translator: Although the data sheet states that you would need at least 3.5V for them to recognize as HIGH level(70% of 5V), many seem to have no problem being driven from a 3.3V micro. With the signal regeneration that each does, it is only […]
cpldcpu writes: What’s pretty cool about these LEDs is that they are diffuse – no more blinding unidirectional light. This might be very useful for indicator lights. Furthermore, you can easily wire them freeform without a pcb. I see a lot of RGB LED cubes coming up… The LEDs come with four leads: VCC, GND, […]
