Smart lightbulbs cost your firstborn child. Which is a shame, because smart lights unlock tremendous potential for home automation, energy savings, and all sorts of cool projects.
If only there was a way to control your lights without breaking the bank…
And now there is! For $19 on Amazon, you can get a 4-lightbulb kit from China that ordinarily is limited to 4 channels from a single remote…but with some creative hacking, can be used to control an unlimited number of channels using an arduino and a very simple RF module!
