Hello,
Ive seen an LCD (hitachi 44780) tester that has an LED indicator when the LCD is working properly it lites up and when the LCD doesnt work it doesnt lite up so Im wonderin where in the LCD circuit, assuming im using a 2 wire to PIC microcontroller configuration (myke predko's style), would i put the LEDs on so that based on the LEDs lite i can say that the LCD is workin fine.
I've manage to break an LCD before :shock: , Ive used a 15V supply w/ LM7805 regulator can someone plz give me more helpful tips on how to prevent more unnecessary voltage entering( im broke my LCD this way) the LCD unit so as not to break it again :lol:
