hi everyone.
i am new to arduino programming.
When i interfaced JHD162A LCD with my arduino (ATMEGA 8) and uploaded the "Hello World "
program in the arduino library,i get blank (no display) in the first row and black square boxes in the second row.
I connected a 5K pot on pin 3 on the lcd and i was able to adjust the contrast of the lcd.
but why this problem ? please help me..
Any help will be appreciated..
thanks in advance..
