Adding Information about traps with the function maps

[StefanL38]

the reason suggesting this is this thread

MIDI instrument - controlling Neopixels (ws2812) with softpots - only 2 out of 3 softpots are controlling pixels as expected

If a program does not work as expected reduce the possible bugs by reducing variety. In the testcode Your variable int calibrationMax[] = { 0, 0, 0 }; is initialised with zero and gets never assigned any other value variable calibrationMin[i] = EEPROM.read(21 + (21 * i)); gets assigned values This means you call the function map with ... map(value,10,0...) Where the second parameter should be a min-value compared to max-value (the third parameter) So if you change the map-functi…

user jim81 gets negative values as the result of the map-function
