Hi i'm new from topic and arduino too.
I buy a LCD 03 from robot electronics.
I read all the post in the forum and i search everywhere in google but i can't arrive to make it work.
I just arrive to get some blinking and wrong character.
I tried all the libraries from Wentz but nothing at all.
I have the correct i2C address to 0x63.
i have a Arduino uno R3 so i plug to pins close to aref.
i waste a week working on it without any result.
Please could anyone that has it working give me sketch and library or help me?
i don't realy know how to solve, thx in advance.
