Block coding¶

piBo Maker uses Blockly for block coding. Besides the standard blocks there are piBo blocks that call the openpibo Python package. The [Python code] button shows the Python code your blocks make.

Note

This page is generated from the IDE toolbox (docs/tools/gen_block_guide.py). Each picture shows the block as it comes out of the toolbox. Everything runs inside piBo. Only the [Collect] category needs the internet, and it is only in the Korean edition.
