SUGESTION!!! use a potentiometer from pin 3 to ground. This is the contrast display. It took me 5 hours to find out that you have to use a potentiometer to edit the contrast otherwise you will not see anyting on the lcd. Just the backlit. Also, I got to see bargled symbols sent to the lcd, but I have not been able to send actual messages to it..
let mek now if you have any success. My email is monstertech5000@gmail.com
