Output Problems

Using Arduino Programming Questions
1

Hi, I'm pretty new to arduino. I'm trying to make a 8x8 led matrix to work with a joystick but i,m getting a weird output from a IF statment. I want the code to do nothing except X or Y are <300 or >700. The IF validates even the x or y are 500.

void loop()
{
  int xValue = analogRead(joyX);
  int yValue = analogRead(joyY);
 
if (analogRead(xValue)>700 && posCol<7){lc.setLed(0,posCol,posLin,false);posCol = posCol + 1;Serial.print( "x"); Serial.print( xValue);goto bailout;}
if (analogRead(yValue)>700 && posLin<7){lc.setLed(0,posCol,posLin,false);posLin = posLin + 1;Serial.print( "y"); Serial.println( yValue);goto bailout;}
if (analogRead(yValue)<300 && posLin>0){lc.setLed(0,posCol,posLin,false);posLin = posLin - 1;Serial.print( "y"); Serial.println( yValue);goto bailout;}
if (analogRead(xValue)<300 && posCol>0 ){lc.setLed(0,posCol,posLin,false);posCol = posCol - 1;Serial.print( "x"); Serial.print( xValue);goto bailout;}
//else if (digitalRead(SW_pin)==0){delay(200);lc.setLed(0,posCol,posLin,true);posCol = posCol - 1;}
bailout:
delay(50);
lc.setLed(0,posCol,posLin,true);

}

You need to post the complete program in your next Reply.

I suspect @AWOL has identified a significant problem - but without the complete code I don't know.

AWOL:
analogRead(xValue)oops

Damn it was so basic :slight_smile:

I doubled the analogread

thank you AWOL
