This attractive illuminated scene can serve as a lamp or a living piece of art for your home.

Environmental Sensing

The NeoPixel strip that illuminates the city scene is controlled by a Circuit Playground Express, and is programmed to react to certain environmental conditions.

Two modes allow the NeoPixel strip to dim or brighten the strip in accordance with ambient light levels, or adjust its color based on the temperature measured by its onboard thermistor.
