Low Power RGB Night Light


Michael of n0m1 Design built this Arduino-controlled night light as a Mother’s Day gift.

A few years back I made a motion sensitive night light as a Mother’s day gift and while it worked pretty well it really chewed out the batteries. And as with all devices that eat batteries it eventually fell out of use. The standby current was around 4 mA due to the common LM324 opamp that was used to amplify the PIR motion sensor signal. The original enclosure was CNC milled from a bit of re-purposed apple which had a former life as a guitar body I built as a child.

Code and schematics on the project page.

    Good post. The design is interesting and it seems nice with its wooden box. Thanks for posting.
