Nokia 5110 LCD Display

I am trying to add a ASC file to an existing sketch. The compiler tells me that there is an problem with my #include statement. The name of the file is font.h. The #include statement reads #include"font.h". Can you help? Please keep it simple. I am a newbe. There are three very good lessons on the Nokia 5110 LCD Display on utube. The second lesson attaches a ASC file to the sketch. I cannot get the ASC file to work with the sketch.

Do you really need to do this? It sounds like you might be watching ancient history. Try the PCD8544 library. If you need a couple of special characters you can use this.

Another graphic option with varying fonts is at Rinkydink

#include <font.h>
