All important parts and files for building an addressable smart led ring which can be used for displaying the time. This is NOT a complete guide for how to build it yourself and rather a (hopefully helpful) list on what things are needed for someone with sufficient background knowledge interested in building this or something similar.
- Automatic brighness adjustment (using BH1750 sensor)
- RGB+warmwhite addressable leds (SK6812)
- Tasmota web interface
- Control color
- Switch between modes
- View sensor information
- Smart home integration via MQTT
- SCD40 sensor
- CO2 levels (second hand turns red at 1000ppm)
- Humidity
- Temperature (very inaccurate because of internal heating)
- 12 x frame parts
- 12 x frame clippers
- esp and sensor case
- esp8266 d1 mini (some may have different fits and may not be compatible with the provided PCB!!!) link
- 4 x sk6812 light strip (RGBWW; 1m; 60 leds; IP30) link
- EasyEDA PCB (you have to order yourself here using the EasyEDA_pcb.json)
- SCD40 sensor link
- BH1750 sensor link
- ESP Home:
esphome run lightring.yml - Custom Tasmota version
- Clock mode:
scheme 5 - Set amount of leds:
pixels 240 - Make clock go counterclockwise:
setoption16 1 - 2 channels for RGB and WW:
setoption68 1 - Set hand colors (for WW set R=00 and G=B, e.g. RGB <- 001212):
- Second (white):
color3 FFFFFF - Minute (warmwhite):
color4 00FFFF - Hour (warmwhite):
color5 00FFFF - Marker (off):
color6 000000
- Second (white):
- Let second hand turn red if CO2 levels too high:
Rule1 on SCD40#CarbonDioxide>1000 do color3 #FF0000 endon on SCD40#CarbonDioxide<=1000 do color3 #FFFFFF endon" - Rotate around 60 pixels:
rotation 60
- D2 -> I2C SDA
- D1 -> I2C SCL
- D5 -> WS2812
