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.
|
||||
|

---Shift Register 74HC595---
|
||||
* SR Pin 14 to Arduino pin 2
|
||||
* SR Pin 12 to Arduino pin 3

* SR Pin 5 to MOSFET gate
|

* SR Pin 6 to Enable
|

-----LCD HD44780-------------

* 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
|
