I’m relatively new to all the Arduino programming, but managed to get pretty much everything I needed to do, done. However, this LCD thing is doing my head in.
I’ve connected an LCD (SparkFun ADM1602k, 16x2) and it works fine, backlight, contrast etc. However, when I send some .print() to it, it fails and gives me incomprehensible garbage. I knew there was some information we could get from these scrambles so I added a picture to the thread for your perusal.
I’ve taken a look at the wires, I even re-soldered to make sure the structure of each pin was sufficient. Not so sure about the jump wires (this isn’t going through a bread board). All wired up as per the Arduino tutorial on their website (and no, I didn’t accidentally read the thing upside down).
Any help or advice from you experts is welcomed - I’m a total noob!
All the very best.
