*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...
Dek's RGB to Component Transcoder (17/5/2020) - This schematic and PCB has been designed to convert a video signal from RGB format to Component (Y,Y-r, Y-b) format. This signal is typically used for retro video game consoles and arcade boards.
You can find the public github here: https://github.com/dekkit/RGB-to-Component-Transcoder
Component video can be found in modern CRT TVs...
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.
3 Channel (RGB) 10A/chan, WeMos LED Driver 12-24V
Specifically designed for 24V RGB LED strips
Designed to be DIN Rail mounted in a small enclosure next to a 24V power supply for use for larger home LED installations (under cabinet, Decks, etc)
Hosts a webpage to interface to change colors from a smart phone.
rx/tx and I2C broken out for external interfacing specifically a for nextion display...
A very small unit for controlling RGB LED Strips.
All outputs should be pwm and i personally use OPENHAB2 for my MQTT Broker.
Flash with espeasy or Tasmota and set up to your own system.
I have several of these around my home and they work perfectly everytime.
Tried and tested :)
It has a space for a PIR sensor and a room temperature sensor
Will work with any MQTT Broker if set up for it.
Universal board for LED control.
- Atmega8/328 on board with programming connector
- PCA9685 for 16 channel PWM up to 1.5kHz (eye-safe frequency), 12 bits per channel
- cheap ULN2003 with paired outputs for 1A per channel (2-3 meters of RGB 5050 strip per connector)
- or SOT23 MOSFETs if you need more power
- BT05 bluetooth module or MAX485, control by wire or wireless. DMX512 is possible.
This is a second version of Christmas Tree Controller. It is using Arduino Pro Mini and two TLC5940
For LED wiring refer to "Christmas Tree LED Wiring" project, LED v2
PCBs is just for reference. I didn't order/made one.
Program for Arduino is not ready yet. I will publish it as attachment or provide a link later.
