Hoping someone has seen this before. Working on my first Nano project and I was succesful in sending text to a 1602 display. I received a couple of 2004 displays to and swapped one in. I updated the code and everything runs ok but I get two characters at EOL with bars in them:
Any help would be appreciated
Did you use println?
(It's hard to tell from the code you didn't post)
Yep
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 20, 4);
...
lcd.begin(20,4);
lcd.init(); // initialize the lcd
lcd.backlight(); // Turn backlight On
...
lcd.setCursor(0, 0);
lcd.print("Garage: ");
lcd.print(garageTemp);
lcd.println("F ");
lcd.setCursor(0, 1);
lcd.print("Humidity: ");
lcd.print(garageHumidity);
lcd.println("% ");
So, don't use println.
Please remember to use code tags when posting code.
I'd be a tad worried about your "freezers", if I remember the Fahrenheit scale correctly.
I feel like such a noob, that did the trick. Thanks!
