Make JSON Object

File:TArduinoMakeJSONObject.png

Summary

Use this component to construct a JSON-formatted text object from multiple typed inputs.

Description

The **Make JSON Object** component generates a JSON object string by assembling values from various typed input elements—such as text, boolean, integer, analog, null, object, array, and custom JSON entries. Each included element produces a corresponding field in the output JSON. When **Only Modified** is enabled, only elements that have changed since the last output are included, reducing output noise. The **Enabled** property toggles the component's operation: when disabled, it passes through input unmodified.

This component is especially useful for dynamically building structured JSON payloads for APIs, web services, or serial output—ensuring only relevant changes are transmitted or logged.
