To get your pacman effect you wanted, you would first write your text to be eaten. Then loop i from 0 to 15. on each step set the cursor to i-1 (except 0) and print a space (to clear the previous pacman) Then if i%2==0 (check for even) to get if your mouth should be open or closed. and write that pacman character. And then delay. This will advance your pacman across the screen, overwriting existing characters as he goes.

A more efficient way of switching between open mouth and closed mouth would be like this:
Boolean mouth=0;
stuff
stuff
stuff
void loop(){
stuff
stuff
mouth=!mouth;
stuff
}
because the Boolean gets switched between 0 and 1, it will automatically switch between open and closed mouths...

Hey, Im working on a project were I would be turning my LCD into a mouth that moves in time with a .WAV file... any advice on how to create a full mouth animation? i found your tutoral helpful explining the 0, 15 etc. but i didnt understand how you defined the first block ? 0b? 1b(block 2) 2b(block3) etc ?

I made a neat animation on my LCD, and I didn't know how to make a backspace, and I didn't know work with setcursor, so I did

lcd.clear();
//delay if needed
lcd.print("text");

Which did pretty much the same thing but took up a lot of lines of code.

Hi Tom, I'm working my way through your videos and wondered if you ever got pacman to scroll by, eating the letters.  I'd be happy to write it for you, it might be a nice intro for your videos. Just reply with the code you have so far.  Really enjoying the videos, thanks for making them!

i can't get my char to show up i created my char in the set up and
lcd.setCursor(13, 0);
lcd.write(customChar, (0)); in the loop and it dosn't show up
plz help

[FullFledged]

So how do i get a custom char to appear once Or even better : appear without using void loop?
I mean is there a simple way to just "lcd.print" the custom char?

"call of overloaded 'write(int)' is ambiguous"

This is a better tutorial for people, showing exactly how everything is done for beginners (see Glen Matthews post towards the end)
