I have connected 1k resistor between lcd pin 1 &3

you can also put your desired value

Step 4: Connection

lcd pin 16 -24th pin of mega and followed by other pins in the same row

Step 5: Burn It

upload the code and enjoy connection less LCD

LCD doesn't work correctly when pins 26 to 32 aren't set LOW. I suggest adding the following code (this worked for me :) )

pinMode(26,OUTPUT);
pinMode(28,OUTPUT);
pinMode(30,OUTPUT);
pinMode(32,OUTPUT);

digitalWrite(26,LOW);
digitalWrite(28,LOW);
digitalWrite(30,LOW);
digitalWrite(32,LOW);
