![]() ![]() Hi galdorin, It's just a floating point version of the map command. With this line and the 5 arguments in the function, what we’re saying is: take the potentiometerValue from the range 0-1023, to the range 0-255. Nano is a particularly small Arduino especially for working with stitch cards. fromLow: the lower bound of the value’s current range. A000005 Arduino Nano ATMega328 map : : Electronics & Photo. ![]() Syntax map (value, fromLow, fromHigh, toLow, toHigh) Parameters value: the number to map. Fractional remainders are truncated, and are not rounded or averaged.

Sketch was uploaded into Arduino using program software ArduinoIDE. float fmap (float x, float inmin, float inmax, float outmin, float outmax) Then x would be the same as x in the main code, inmin would be 0, inmax would be 1023, outmin would be 0.05 and outmax would be 10.00. int brightness map(potentiometerValue, 0, 1023, 0, 255) To do the same thing, you could also use the Arduino map () function which can put a number into a different range. The map () function uses integer math so will not generate fractions, when the math might indicate that it should do so. ![]()
