Message Wand - The message wand is a good PIC introduction as it is a simple
project yet illustrates many aspects of the PIC usage. Used at night, the wand is
swung around above the head, and to onlookers spells out a short message in the air
using flashing LEDs. It could also be used with a handle and spun round like a
traditional soccer rattle (can you still get those?) though great care must be taken
if you do this....(circuit added 04/04/04)
Microcontroller drives LCD with just one wire - (Design Ideas - EDN, 12/3/2007 A
Microchip PIC10F family microcontroller sparks an HD44780 LCD using a single I/O pin.
(electronic design idea added 9/2008)
Picxie 2 - 8x8 Animated LED Signboard - The firmware supplied in current
sourcecode archive is VERY BASIC. I do intend to draw more patterns. However, a vast
workload coupled with possible emigration has put finished firmware on hold. Please
do go ahead and build this circuit though supplied firmware is fully functional.
You can have hours of fun designing your own patterns and effects! Uses PIC16F84
