I used a 1602 LCD with a shield (just four pines). It was fine, but after a fall down, it has a problem. When the number of characters exceeds 8 or 9, right half of the LCD become white (after about 100 ms).
What do you think?
To buy a new one.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Can you please post a picture of your project?
(Good to hear you got the stepper working)
the circuit is OK! I had checked it and worked! I guess some of the pin headers are damaged!
