PIC microprocessor drives 20 LED dot or bar-graph display -
1-Sep-06 Issue of EDN Indicator circuit features low cost and
minimal component count....[Design Idea by Noureddine Benabadji,
University of Sciences and Technology, Oran, Algeria; Edited by Brad
Thompson and Fran Granville] |
|
PIC NIC Ethernet Controller - PICNIC is a project to add 10BaseT
Ethernet controller to PIC17F877, and it can run as an network-enable
device. This project is based on tristate's PICNIC product. And I
just change the temperature sensor's circuits to improve the precision on
A/D convert….(electronic schematic added 11/08) |

PIC NiCad Battery Charger - Circuit designed by Peter Hayles.
This cheap and easy to build NiCd/NiMH Battery Charger is suitable for
automatically charging a wide range of batteries for many applications.
Proper chargers are usually expensive and cheap chargers
supplied....(added 10/05) |
|
PIC Phone Line Controller v2 - This is a newer version of
previous device with a single relay. This one can have up to 6
relays and 6 sensor-state inputs. The task was to build a device that
connects to the phone line….(design added 11/08) |
|
|
|
PIC PIN/ Port Extender - This circuit based around 74LS154 will extend PIC
/ AVR microcontroller output PINs from 4 to up to 16. It can also be used for
extending parallel port output pins. ….... |

PIC plots pixels sans controller - 02/16/98 EDN-Design Ideas....It
is sometimes desirable to display the output of a PIC µC graphically, rather
than numerically. However, the operation increases system complexity and
expense. In addition to the LCD itself, you usually need a graphics
controller and at least 1 kbyte of RAM. However, you can obtain a
satisfactory plot....File has many circuits, scroll to find this
one....[Design Idea by Daryl Christopher, Juniata College, and Tom Fisher,
Inexpensive Systems, Huntingdon, PA] |
|
PIC Programmable Security System - This project uses the 12F675,
it was chosen because of its low cost, A/D convertor and flash memory.
This security system was designed….... |

PIC Programmer - The project presented here will provide you with
the ability to program a PIC from your parallel printer port on your PC
computer. To program a PIC is relatively simple. A standard 5 volt DC supply
voltage is connected…. [Michael A. Covington] |

PIC Programmer - As you can see, only a few standard elements are used and
the hardware is very simple to build. So here are only a few words about hardware.
Supply voltage can be either AC or DC. Voltage Vdd must be between 4.5 and 5.5 V. For
this purpose integrated stabiliser 78L05 (Vdd=5V) is used. It has current limitation
(protection) 100 mA and with this feature protects inserted PIC from damage in case
something is wrong connected. Programming voltage 13V is provided with 78L08....[Bojan

PIC Programmer 2 - (electronic circuit added 7/03) |
|
PIC Programmer sent by FcoArroyo - Francisco Arroyo Garcia sent this
schematic as an alternative to program MICROCHIP PICs. This programmer is a
JDM-based and works fine to program the PIC 16F628A. (design added 12/06) |
