Математически функция map() может быть записана так:
long map(long x, long in_min, long in_max, long out_min, long out_max)
{
return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
}
//а если заменить long на float или double, то она будет работать с плавающей точкой
//и соответственно изменить имя функции, что бы оно не пересекалось с родной библиотекой ардуины
void loop() {
analogWrite(col, xCol);

analogWrite(baza, xBaza);

}
}if(xBaza != xBaza0 && xBaza != -1) {
