If with multiple condition

Using Arduino Programming Questions
1

Hello i am beginner so, can i have multiple condition?

i create this code for joystik

  if (analogRead(VRX) > 0) $$ (analogRead(VRX) < 750) $$ (analogRead(VRY) < 514) $$ (analogRead(VRY) > 250 ) {
    mysku_dolu();
  }

it is only part but this if have error

Where did you find the $$ syntax ?

$$ is nothing, I think you mean to use &&.

I also recommend some syntax changes for the sake of readability.

Use local variables to store analog sample in. This also runs faster as you take one sample and not two per axis.

int sampleX = analogRead( VRX ) ;
int sampleY = analogRead( VRY ) ;

For complex if statements I also recommend to use more lines and organize it properly.

if( sampleX  >  0 && sampleX < 750
&&  sampleY > 250 && sampleY < 514 )
{
    mysku_dolu();
}

Also, I usually recommend to use constants like, but if these values are only used here... you might as well leave it be.

const int xLow  = 0 ;
const int xHigh = 750 ;
const int yLow  = 250 ;
const int yHigh = 514 ;

And avoid abreviations. I know nothing of the context, so I cannot start to guess what VRX/VRY means or whatever mysku_dolu is supposed to mean?

Regards,

Bas

presumably "myska dolu" means something relevant in your language?
