- Demonstrates the use a 16x2 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.
+ Demonstrates the use a 20x2 VFD display.  The SPI_VFD
+ library works with all VFD displays that are compatible with the

- This sketch prints "Hello World!" to the LCD and
- uses the cursor()  and noCursor() methods to turn
- on and off the cursor.
- 
- 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 resistor:
- * ends to +5V and ground
- * wiper to LCD VO pin (pin 3)
+ This sketch prints "Hello World!" to the LCD
+ and shows the time.
  
+  The circuit:
+ * VFD Clock to digital pin 2
+ * VFD Data to digital pin 3
+ * VFD Chip select to digital pin 4
+ * VFD VCC (power) to 5V
+ * VFD Ground (power) to Ground
