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.
STM32 RGB generic control module (the one found on the cheap online retailers). Paths and some parts may not be accurate as they do vary, but the schematic was recreated based on the P9813 datasheet for the +12V power source. Note that this chip takes in power from 9V all the way up to 30V or so (check datasheet for specifics), and that the paths/chip locations are not perfectly representative of...
It is simple module to control RGB strips. You can use diferent MOSFETs (but 3 - sourse 2 - draine 1 - gate).[Sketch for Arduino](https://github.com/ParasolkaJeck/Arduino_RGB_controler). You can don't use diod.
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 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.
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.
