WS2812b LED Driver with Raspberry PI Cape for Staircase Lighting Effects
The Raspberry PI cape (incorporating a signal level converter and protection resistors/diodes) has 3 output
channels and 3 input channels. Its primary purpose is to drive 2 independent WS2812b LED light strings using 2 PWM
channels. Its initial application is staircase lighting effects that include slowly changing colors in the
background. Once motion is detected, an "up stair" or "down stair" lighting effect will be triggered.
CEC to USB and RS-232 converter/bridge, connects to an HDMI cable.
Both receive and send hex-codes on the single wire CEC bus present in HDMI cables. The USB tty (serial-port)
device is compatible with both Windows and Linux without additional host drivers.
