Stand-alone pixel controllers are able to control individual LEDs (or pixels).
There are two different types of stand-alone controllers:
preprogrammed controllers: They already contain permanently stored programs that you can play. Some of them have an App or remote control with which you can select the individual programs.
- programmable controllers: these controllers are used e.g. operated by means of an SD card. The SD card contains the programs you have programmed on the PC. Some controllers can also be programmed via USB or via the network.
These controllers can thus be versatile, e.g. Use advertising displays or ambient lighting without having to use a computer for control purposes.
