Edges

Edges allow you to connect nodes together to create a flow of data.

Edges are created by dragging a connection from one node's handle to another node's handle.

Examples

Flows can be simple or complex, depending on the number of nodes and the connections between them.

Simple flow

In this example, we have a simple flow with two nodes connected by an edge. When a button (pin 6) is pressed, the LED (pin 13 (BUILTIN_LED)) turns on.

Complex flow

In this example, we have a more complex flow with multiple nodes connected by edges.

When a button (pin 6) is pressed, the counter increments. The counter value is then mapped to a range of values. If the counter value is greater than N, the LED (pin 13 (BUILTIN_LED)) turns on. Else, the piezo (pin 11) buzzer turns on.
