Digital Call Sign Annunciator - (electronic circuit added 4/05)
|
|
Dot/Bar Display Driver - The LM3915 is a monolithic integrated
circuit that senses analog voltage levels and drives ten LEDs, LCDs or
vacuum fluorescent displays, providing a logarithmic (added 07/07/07)

Dual Digital Thermometer - This application shows how to use the
PIC16F877 to control, and interface with the Dallas DS1820 1-Wire™ Digital
Thermometer. If you missed the LCD connection schematic for these
experiments, …(added 11/05) |

Easily Display Bit Map Images on Small Graphic LCDs - 11/19/98
EDN-Design Ideas.....Combining a high-level language, such as Microsoft
Windows, with low-level assembly code or C++ code allows you to display
perfect bit-map pictures on your small-graphic LCD screen. You can use
Microsoft Paint or any other bit-map-generating ..... [Design Idea by Todd
Fitzsimmons, Densitron Corp, Santa Fe Springs, CA] |

Ericsson Cell Phone Display GA628 - The GA628 display provides a
12 character alphanumeric display , some icons in the second line and
power consumption of some 100 uA. It can easily be connected to the
hardware, simply.... [Robert Tyrakowski] |

LCD Clock/Calendar - LCD Display with Date and Time, 12hr format. (circuit
added 12/04) |
|
LCD Display - (application / block diagram added 6/07) |

LCD Display with Minimum Mass Wireless Coupler - Its an adaption of the 2X
16 LCD project, by adding a fettite loop antenna, two resistors, and a capacitor. Here
the display shows the output of the 10 bit scanning voltmeter with Minimum Mass
Wireless Coupler. (ATtiny2313, AT90S2313)…..... |
|
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
Idea by Robert Wells, ETR, Moab, UT] |
|
LCD Interface Takes Two Wires - 03/26/98 EDN-Design Ideas.....Alphanumeric
LCD modules can provide an attractive display for a project, but their parallel I/O
lines require a large number of outputs from a �C. For example, a direct LCD interface
would consume all of the I/O pins..... [Design Idea by Ed Maste, Jem Designs,
Pickering, ON, Canada] |

LED Clock (Jose Pino) - 12Hr LED clock using 16F628. Also, schematic to
build a Jumbo clock is included..... |

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....
|
|
LED Relay Timer - This circuit provides a visual 9 second delay using a 7
segment digital readout LED. When the switch is closed, the CD4010 up/down counter is
preset to 9 and the 555 timer is disabLED with the output held high. When the switch
is opened,.....(circuit / schematic design added 6/06) |

LED Sign - uses two LED arrays to form a 7 X 10 matrix. It produces moving
messages or animations stored in an EPROM...... |
