well now its acting weird and i didn't change anything. If i have the lcd tx pin to the ground like the playground tutorial shows there is a double bar (almost looks like a new paragraph symbol before the welcome screen and the program dosent get transferred to the display but if i unplug it from ground it receives it This is not how it was earlier. so now to get the same results as my above post i have to leave the displays tx wire unplugged completley from the arduino. Why is this so hard I cant find jack for any good serial lcd tutorial all the ones i find are hopelessly outdated or have like 50 different commands some hidden some not with cryptic remarks and i am supposed to know what all that is.
so now the lcd isnt even acting like it was earlier so I dont even have a solid reference or starting point anymore who knows whats going on. any help?
