Map Range Analog

Summary

Maps an analog input from one range to another output range, including negative ranges and reversed scaling.

Description

The Map Range Analog component scales an input analog signal from a defined input range to a specified output range. You can set any values for both the input and output ranges, including negative numbers. It also supports “reverse” mapping, where the input range is larger than the output range, or where the output decreases as the input increases. This makes it extremely flexible for adapting sensor values to actuators, normalizing signals, unit conversions, or inverting control responses.

• • Examples:**
• Input Range: 0 to 1023, Output Range: 0 to 5 → Converts a 10-bit ADC value to voltage.
• Input Range: -1 to 1, Output Range: 0 to 100 → Maps normalized signal to percentage.
• Input Range: 0 to 5, Output Range: 5 to 0 → Inverts the input signal.
