Adalight for Circuit Playground
Revisiting a classic project with Circuit Playground
by Phillip Burgess
One of my first projects with Adafruit was Adalight, an ambient lighting effect for media PCs, similar to the Ambilight feature of mid-2000s Philips TVs. Basically, matching what's on the screen to a set of background lights to make the display pop! This pint-sized version of our earlier Adalight project brings easy ambient media lighting to laptops and small all-in-one PCs.
