Block: Map

Type: math_map

Transform sensor readings and data values by scaling them from one number range to another. Essential for IoT projects that need to convert raw sensor data (like 0-1023 from Arduino analog pins) into meaningful units (like 0-100% humidity), or translate between different measurement systems. Perfect for normalizing data, creating percentage values, or adapting sensor outputs to match your specific needs.

Inputs

Value

The raw number you want to convert to a different scale. Examples: sensor reading of 512 (from 0-1023 analog range), temperature of 25°C (for Fahrenheit conversion), or any numerical data that needs scaling to a new range.

From_range

The original scale that your input value currently represents. Examples: (0,1023) for Arduino analog sensors, (0,255) for RGB color values, (-40,125) for temperature sensor ranges, or (0,100) for percentage data that needs different scaling.

To_range

The new scale you want to convert your value to. Examples: (0,100) for percentage displays, (0.0,1.0) for normalized values, (32,212) for Fahrenheit conversion, or any target range that matches your display needs or system requirements.
