-A small library/program for using the 1602 LCD display in 4 bit mode.
+A small library/program for using the 1602 LCD display in 4 bit mode.
+
+## Hardware:
+
+- LCD 1602 ADM1602K-NSW-FBS-3.3v or ADM1602K-NSW-FBS-5.0v
+- AVR Micro-controller
+
+## Supported Controllers:
+
+List of supported controllers:
+___
+- ATMega48 
+- ATMega88 
+- ATMega168 
+- ATMega328
+
+___
+
+## Usage:
+
+```C
+#include "AVR_ATMEGA_1602LCD.h"
+
+void lcd_begin() {
+    set_lcd_two_line();
+    return_home_lcd();
+    clear_lcd();
+    
+    //Do stuff.
+}
+```
+
+## RoadMap:
+
+1. define all functions for the data sheets instructions.
+2. Change cmd_lcd() function to only be called once instead of nibbles.
+3. Make functions port indapendant.
+4. ADD function to print strings
+5. ADD function to display bit images
+6. ADD function to act as a loading screen.
+7. ADD animations
+8. ADD PWM control for contrast
+9. ADD PWM control for backlight
