Low-speed, high resolution pixel poi based on WS2812B LED strip.
This project was made as a challenge to see how small I can go with conventional soldering techniques, this uses an Attiny85 with a QFN-20 package.
Este es un proyecto para ver que tan pequeño podía diseñar un circuito y culminarlo con soldadura convencional. Usa un Attiny85 con empaque QFN-20.
NeoPixel led strip controller, designed especially for led suits. It can:
- display animation - sequences of frames at regular (given) interval,
- switch animations on MIDI event - note on/off, velocity used for brightness adjust,
- MIDI over UDP over WiFi (UDP broadcast so far, but i'm working on multicast),
- use regular SD card to storage animations.
[These guys use them] for...

By Arduino nano, control RGB5050 light colorful scroll.
From S1 to S4 was then performed, four buttons to control the beam of the rolling way, and switch to a different jumper mode, can display different colors of lig...
*ESP8266 and WS2812b Individually Addressable RGB LEDs [12 bit]*
**EspRing** is a 12 bit neopixel ring using **ws2812b** RGB LEDs and to control the LEDs there is an **ESP 12E** module builtin. So basically you'll get a *neopixel ring which has a onboard microcontroller*. Since WS2812B leds are individually addressable so we just need only one data pin from the microcontroller along with VCC and...
<p>This project is intended to provide a mounting spot for a Teensy 4.0 and then send the signals pins to a MOSFET for each of the signal pins 1-12. While also giving a plug to bring in 12V power and 3 RJ-45 connectors to allow the power to be distributed. The assumption is that the total load will be no more than 3A and the MOSFETs will be 100% on at 3.3V</p>
Christmas tree ornament with (mostly) just a small number of through-hole components. Great for beginners. Might need a more experienced person to install the ATTiny841 and program it. There is an (optional) programming header to make in-circuit programming easy.
Unlike lots of other similar projects, the use of a micro-controller allows for smooth fading of the LEDs which makes for much more nat...
A dual microcontroller board for controlling "Neopixel" LEDs, with one micro dedicated to driving the LEDs while the other micro is busy reading push buttons, polling rotary encoders, reading IR remote signals etc etc.
The microcontrollers -two atmega328s -communicate with one another over their I2C bus. The very short wire run negates the need for the usual pull up resistors on the bus.
