robotling_lib

"robotling" is a simple circuit board to control small robots, mainly for educational purpose. This repository contains robotling-related hardware and software libraries.

Note: Several of the drivers are based on code developed by Adafruit; for details on source, copyright, original authors etc., see information in respective file header.

For an overview of some of the supported hardware, see "Sensoren etc." (in German).

Note: Some of the drivers (e.g. TeraRanger Evo Mini, which requires an UART port to access its full functionality) are not compatible to the current robotling board.
