RaspberryLight

Make your Raspberry Pi to a Wi-Fi controllable LED Light

Make your Raspberry Pi to a Wi-Fi controllable LED Light using LED stripes with WS 2811 controller. This software enables the raspberry to provide a web server interface (HTTP / Rest) for controlling the connected LED stripe. That project bases on the WiringPi lib, Indy for Lazarus and also on the Tinkerforge bindungs for Lazarus. The Stripe must be connected with the Tinkerforge Masterbrick and the LED-Stripe bricklet. WiringPi is used to control the GPIOs for some feature and Indy (Internet Direct) is used to support all network feature like UDP-broadcasting and handling the HTTP-requests. The development platform is Lazarus.
