Nodes

Nodes are the building blocks of any flow. Think of them as puzzle pieces that you can connect together to create interactive projects.

Each node does a specific job - some read information (like a button press or sensor reading), some control things (like turning on a light), and some process information (like doing math or making decisions). You can connect nodes together using edges to create a flow of information and actions.

For example, you can create a flow that reads data from a sensor, processes the data, and then sends the result to an output device like an LED light.

Parts of a Node

Nodes are connected with edges (the lines between nodes) to form a flow. Each node has connection points called "handles" where you can attach edges to connect nodes together.

Input handles

These are the connection points on the left side of a node (shown in blue). You connect other nodes to these handles to send information or signals into the node. For example, you might connect a button node to an LED node's input handle so the LED turns on when the button is pressed.

Output handles

These are the connection points on the right side of a node (shown in green). These send information or signals out to other nodes. Each node has different types of outputs depending on what it does. For example, a button node might have an "on" output and an "off" output.

Node value

This is the visual display in the center of the node that shows what the node is currently doing or what value it has. This could be a number, a switch that's on or off, a color, an icon, or other visual indicators. It helps you see what's happening in your flow at a glance.

Settings

You can customize how each node works by clicking the settings icon (usually in the top right corner of the node). This lets you change things like which pin a sensor is connected to, how fast something happens, or what values to use.
