9. Working

10. sensorValue = analogRead ( potPin ); // read the analog in value: outputValue = map( sensorValue , 0, 1023, 0, 255); // map it to the range of the analog out:

11. if ( outputValue >= 30 ) // 30 is ADC Value { digitalWrite (ledpin1,LOW); lcd.setCursor (0,1); //Set cursor to first column of second row lcd.print (" Load = 12.5%"); } else { digitalWrite (ledpin1,HIGH); } if ( outputValue >= 60) { digitalWrite (ledpin2,LOW); lcd.setCursor (0,1); //Set cursor to first column of second row lcd.print (" Load = 25.0%"); // title of sorts } else .. . . . . .

12. . . . . . . if ( outputValue >= 240 ) // 240 is ADC Value { digitalWrite (ledpin8,LOW); lcd.setCursor (0,1); //Set cursor to first column of second row lcd.print (" Load = _100%"); // title of sorts } else { digitalWrite (ledpin8,HIGH);
