Matrix LED Display - A mini display using an array de 5x24 LEDs using Microchip
PIC 16F628. (added circuit 10/04)
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)
MOSFET Serves as Ultrafast Plate Driver - 10/03/02 EDN Design Ideas / (added
1/05)The circuit in Figure 1 provides a 20-MHz square wave across a set of highly
capacitive ion-deflection plates in an experimental instrument. To get the required
deflection, the plate voltage must be 20 to 30V, much higher voltage than conventional
logic or driver families can provide....
