Constant

A Constant node provides a fixed number that never changes. Think of it as a number you set once and it stays the same.

Examples:

• Set a constant value of 100 to use as a threshold for comparisons
• Use a constant value of 5 to multiply sensor readings by
• Provide a fixed brightness level (like 128) for an LED

This is useful when you need a specific number in your flow that doesn't come from a sensor or change over time. You can combine it with the Calculate node to do math - for example, multiply a sensor reading by your constant value.
