thisexampleFunctions can also handle negative numbers, such asy = map (x, 1, 50, 50,-100);is also valid and works well.Also effective and correctThe map () function uses integer math so would not be generatefractions when the math might indicate that it should does so. Fractional remainders is truncated, and is not rounded oraveraged.The map () function uses integral types, so no fractions are generated, and fractions are truncated, not full or average (?). ）Parameters parametersValue:the numbe

Analogread (), and the detected voltage (0-5V) is mapped to a digital (0-1023) by a number-to- analog conversion technology (ADC) . If the output of the piezoelectric element exceeds a certain limit value (indicating that the vibration has reached a certain strength) your board will be output through the serial port "detected vibration."
