I'm writing code on Arduino (very similar to C, which I don't know, or very little), and I have a little issue concerning the switch/case statement.
I need my Arduino to do this or that depending on the values of a potentiometer (0 to 1023). However, I have no clue how to tell it case "0 to 200". For example, I tried
case 0..250:
blablaSomeCode;
break;
And so on... How can I do it?
I don't really want to write case 1 case 2 case 3...
You will have to use a cascade of if's (also/especially if your value is a floating point number)
int value= ...;
if (value>=0 && value<=250 {
// some code 0..250
}
else
if (value>250 && value<=500) {
// some code 251..500
}
else
if (value>500 && value<=1000) {
// etc.
}
else {
// all other values (less than zero or 1001...)
}
