# Standard block

Systems of blocks are easy to set up. You can drop blocks next to each other so that their terminals are connected, or drop them a little way apart and wire them up.

The simplest system consists of an input block and an output block (left-to-right), but processing blocks can be used to combine and compare inputs in order to control the output.

Tips for use:

- Click on a block to open its pop-up and see its contents.
- Create your own block using one of the custom blocks from the My Blocks folder in the Contents Pane.
