Nightlights are a great way to calm children who may be afraid of the dark, as well as to avoid stubbing your toe on furniture in the hallway. However, in this day and age of connected everything, they can do so much more. [Andy] came up with a great way to do just that, creating an advanced networked solution to suit his needs.
[Andy’s] nightlight serves not just in the usual fashion, but also as an indicator for his children. Depending on the time of day, the colour changes, indicating whether it’s time for bed, or also, if it’s too early to get out of bed in the morning and start watching cartoons. Each nightlight around the house runs on an ESP8266, which lights up using a set of WS2812B LEDs. The ESP8266 decides on colour values based on commands from a basic webserver running on a Raspberry Pi, updated every minute. This gives [Andy] the flexibility to make changes in one place, that then automatically roll out across the Nightlight Network (TM).
It’s a fun way of teaching the kids not to ruin a good Saturday sleep in, as well as serving as a fun colourful nightlight, too. Of course, luxury smart nightlights are becoming a thing, as this teardown of a Bluetooth unit shows. If you’ve built your own, be sure to drop us a line!
