Hey
I have been connecting an LCD to Arduino but I made a mistake:
I have swapped D6 with D7 and now LCD is showing only rectangles.
Is it damaged for good or is there a way to fix it? I don't know, maybe reset it somehow or idk... thanks in advbvance!
I have been connecting an LCD to Arduino but I made a mistake:
Code:
/*
LiquidCrystal Library - Custom Characters
Demonstrates how to add custom characters on an LCD display.
The LiquidCrystal library works with all LCD displays that are
compatible with the Hitachi HD44780 driver. There are many of
them out there, and you can usually tell them by the 16-pin interface.
This sketch prints "I <heart> Arduino!" and a little dancing man
to the LCD.
The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* 10K potentiometer:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)
* 10K poterntiometer on pin A0

Based on Adafruit's example at
