Moonlamp Base with WS2812B and Arduino Nano

thingiverse

This is a base for a small to medium moonlamp. https://www.thingiverse.com/thing:2955930 It holds an Arduino Nano 3.0 and a WS2812B 5x5mm LED module for illumination. A simple arduino-sketch is attached which is just a slightly modified version of the Adafruit Neopixel strandtest. Be aware it is using a RGBW LED module. If using RGB only, please modify accordingly. ===================================================================== UPDATE as of Dec 23 2019: I added a second sketch called WS2812B_moonlamp_EEPROM.ino. With this sketch, yoi have 10 different modes: 1 White 2 Yellow-Orange 3 Red 4 Green 5 Blue 6 Yellow 7 Magenta 8 Cyan 9 Rainbow (repeat permanent) 10 White 7.5s - Rainbow - Yellow 7.5s - Rainbow (repeat 10) On boot, light show 2 seconds blue, 2 seconds red then number of white blinks indicate mode as described above. Powercycle increases modenumber. If modenumber was 10, an increase leads to mode 1 Power on and power off at first blue light decreases modenumber. If mode was, a decrease leads to mode 10. Power on and power off at first red light resets mode to 1 (white). This sketch uses inbuilt EEPROM of Atmega328P. ====================================================================== Use two M3x10 screws to securely attach the cap to the base. Secure LED-module in place with a drop of superglue or a tape. OpenSCAD file attached for easy modification. Enjoy!
