ShiftLCD Library - Autoscroll
Demonstrates the use a 16x2 LCD display. The ShiftLCD 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 demonstrates the use of the autoscroll()
and noAutoscroll() functions.
The circuit:
---Shift Register 74HC595---
* SR Pin 14 to Arduino pin 2
* SR Pin 12 to Arduino pin 3
* SR Pin 11 to Arduino pin 4
* SR Pin 8 to Ground
* SR Pin 16 to +5v
* SR Pin 13 to Ground
* SR Pin 10 to +5v
-----Shift Reg to LCD--------
* SR Pin 15 to D7
* SR Pin 1 to D6
* SR Pin 2 to D5
* SR Pin 3 to D4
* SR Pin 5 to MOSFET gate
* SR Pin 6 to Enable
* SR Pin 7 to RS
-----LCD HD44780-------------
* Vss to Ground
* Vdd to +5V
* Vo to 10k Wiper
* R/W to Ground
* 5v to +5v
* Gnd to MOSFET Drain
------N Chanel MOSFET--------
* Source to Ground
* Gate to SP Pin 5
* Drain to LCD Gnd
* 1k Resistor Between gate and source
