LCD 2 USB - LCD2USB is a open source/open hardware project. The
goal of LCD2USB is to connect HD44780 based text LCD displays to various
PCs via USB. LCD2USB was meant to be cheap and to be made of easily
available parts. It is therefore based on the Atmel AVR Mega8 CPU and does
not require any difficult to obtain parts like separate USB controllers
and the like. …..... |

LCD Interface Saves µC I/O Pins - 12/12/97 EDN-Design Ideas.....Although in
abundant use, mini microprocessers suffer from a low I/O-pin count, which places each
pin at a premium. Interfacing a bus-type device, such as an alphanumeric LCD, can use
most of the I/O pins. Even placing the display in the 4-bit transfer mode..... [Design

LCD Terminal - The LCD Terminal just like a normal terminal, it can connect
to any host via RS-232 serial cable. A PC keyboard must connect to it as the input
device and what ever you type will send to host via RS-232 and display on a 40x4 LCD.
Data receive from host can also display on the LCD unit. You can use this device as
any Unix/Linux machine's console. …..... |

LED Clock with Timer & Solar Panel Regulator - This is a combination digital
clock timer and solar panel charge controller used to maintain a deep cycle battery
from a solar panel. The timer output is used to control a 12 volt load for a 32 minute
time interval each day. Start time is set using 9 dip switches and ends 32 minutes
later. The 32 minute duration is set by selecting the 5th bit (2^5 = 32) of a 4040
binary counter (pin 2). The timer also has a manual toggle switch so the load can be
manually switched on or off and automatically shuts off after 32 minutes....
