Your kit has a microcontroller on-board, which uses software to control the various functions of both the components directly on the board and the various attachments that can be connected. This piece of software is called firmware.

For a beginner, this can be very overwhelming as there are hundreds of potentially complicated files and algorithms programmed to work together. Thus we have have created a firmware application programming interface (API) called PlutoBlocks to help you explore and reprogram the microcontroller firmware with great ease.
