switch

The switch lets us control the path of a marble:

• When there’s a marble C in the checker cell, any marble S in the signal cell goes straight ahead.
• When there’s no checker marble, S moves half a cell left.

We now have a way to make our marbles interact — the first step towards getting roons to manipulate data like a computer.

distributor

Let’s add another roon, the distributor , to spread out the paths a bit more:

The distributor takes up to 3 inputs separated by half a cell, and spreads them out by a full cell.

We’ve seen how the switch can control the path of a — in the next tutorial we’ll meet its strange cousin.
