stray ‘\342’ in program

This report would have more information with

option enabled in File → Preferences.

Did you post the code that is producing those errors ?

#4

Hi

Yes, under Error stray \342 in program

#5

Yep, here is the code:

#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd (0x27, 16, 2);
#define sensor A2
#define wet 210
#define dry 510

void setup() {
Serial.begin(9600);
lcd.init();
lcd.backlight();
}

void loop() {
int value = analogRead(sensor);
Serial.println(value);
lcd.setCursor(1, 0);
lcd.print(“Moisture Value”);
lcd.setCursor(3, 1);
lcd.print(value);
lcd.print(” “);
lcd.setCursor(7,1);
lcd.print(“–“);
int pre = map(value, wet, dry, 100, 0);
lcd.setCursor(10, 1);
lcd.print(pre);
lcd.print(“%”);
lcd.print(” “);
}

#6

Check all these symbols ".
If you copied this sketch from somewhere they can be wrong.
It should be quoted ".

Look at the difference " and ” .
RV mineirin

#7

Did you copy the program from the web, then paste it in the IDE?
If yes, paste it in notepad then copy it again.

#8

Find and replace in the IDE fixes these problems. i.e. Find ” and replace "

#10

Thanks, I now get what you mean, its the quotes, that were wrong (in unicode) I did copy and then pasted it into the IDE.
