PIC plots pixels sans controller - 02/16/98 EDN-Design Ideas - It is sometimes desirable to display the output of a PIC C graphically, rather than numerically.    __ Circuit Design by Daryl Christopher, Juniata College, and Tom Fisher, Inexpensive Systems, Huntingdon, PA

PIC Programmable Security SystE - M - 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 - 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.  __ Designed by Bojan Dobaj http://www.picallw.com

PIC programmer - This is the simple and easy-to-build PIC programmer that I use for many Microchip  (r) microcontrollers.  Only a few parts, JDM Compatible.  I use IC-PROG with this programmer.  I programmed sucessfully the PICs 16F82, 16F628, 12F629, 12F675, 12C50X, also 16F87X series.12/06/04 Corrected connections on 28-Pins.  Thanks to 'Her Masters Voice' & Alisher ! Microcontroller PIC microchip programmer.  JDM compatible.  Before building this programmer, be sure that your serial port  (RS232) have at least 11 Volts.  At least 11 volts is needed to program the Series "C"  (12C50X, 16C84, 

PIC Programmer & TestBed - Easy PIC programming and prototyping.__ SiliconChip

PIC Programmer SCIO Converter - Programming 18-lead surface-mount SOIC PIC microcontrollers can be a quite difficult because access to the leads is not that easy.  This adaptor PC board accepts 18-pin SOIC PIC microcontrollers and plugs directly into a conventional PIC programmer.__ SiliconChip

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.   __ Designed by Jose Pino

PIC Project #1 RS-232 to I2C Interface - The I2C232 provides an RS232 interface to the I2C bus.  The interface uses ASCII commands for use with any terminal program.   The MicroChip PIC16C63 provides the intelligence and both the SCI and I2C peripherials to power the I2C232 adapter. __ Contact: ronrus s@ emicros.com

PIC Serial LCD project-An RS232 serial LCD interface using a standard HD44780 LCD - This project shows you how to create a serial LCD module that you can drive from any serial RS232 interface.   __ Designed by John Main

PIC Tock Video Clock - PIC-Tock is a video clock using a PIC16C61.  In the tradition of Marv Newland's "Bambi Meets Godzilla", there is far too much ROM space spent on credits, which are smooth-scrolled horizontally on the bottom of the screen.   __ Designed by Eric Smith

PIC USB Development Board - Since I wanted to do some USB development work with the PIC18F4550 and PIC18F2550 board  (for projects like my C64 VICE front-end and Atari joystick adaptor) I needed a USB reference board to develop the software.  Initially I ported the Microchip

PIC Web Server Schematic - The schematic for the generic Web Server is available here as shareware.  When you register, in addition to the material on this page, you will also be entitled to the following __ Designed by Ed Cheung

PIC/AVR Programming Adaptor Board; Pt.1 - Do you frequently program microcontrollers with a serial programmer? Want to streamline the process so you can quickly do virtually any micro? Well now you can! Our new Programming Adaptor Board, in combination with an In-Circuit Serial Programmer  (ICSP) , allows you to program most 8-bit & 16-bit PIC microcontrollers as well as 8-bit Atmel AVRs.  It has a 40-pin ZIF socket and is configured with just a few DIP switches.__ SiliconChip

PIC/AVR Programming Adaptor Board; Pt.2 - Last month, we described our new programming adaptor board which works in conjunction with an In-Circuit Serial Programmer  (ICSP) to program most 8-bit & 16-bit PIC and 8-bit Atmel AVR microcontrollers.  Here, we give the details of how to build it and how to use it.__ SiliconChip

PIC12c508 Night Light Saver - Build a device that turn on and off a night light automatically.  Save Energy, No EMI, No Battery, Built-in Lamp Fixture, and Peak Shaving.   __ Designed by Wichit Sirichote

PIC12F675 PIN PONG - This project is based on ideas from Rickard's electronic projects page and David B.  Thomas VCR Pong.  However, I have developed the simplicity even further, eliminating most of the external components.  Using microcontrollers with internal 4MHz clock generator there is no need for the xtal.  The 12f675 part also operates on wide voltage range, and the regulator can be removed.  For game controller, I plan on using the old Commodore 64 style paddless.  They include firing buttons, which I plan on using as power switch and game reset.16F675 has a low power sleep mode with 1nA current consumption, so I plan on using that to switch off.  

PIC12F675-Flashing LED - Simple little circuit for testing PIC12F675 microcontroller.  When you start learning a programming language like C++, Visual Basic or any other language your first step is to write a program that displays "Hello World" on a computer's monitor.  When you start learning how to program PIC microcontrollers an equivalent to that is blinking a LED.

PIC16c505 IR/Wireless Remote Control - Control up to 8 devices by this easy constructable remote control.  It can work as a radio or infrared remote control, depending on the components.  Each device output can be configured to be momentary  (turned on while you press the button) or latched.  Latched outputs can be toggled on/off by one button per channel, or turned on and off by two buttons per channel. __ Designed by Peter Jakab

PIC16F819 Video Microcontroller - PIC Project  Want to add video to your next project?This device uses a PIC16F819 and not much else.  Getting 20 characters to a line is possible by using the SPI port to generate video.  Neat trick, eh? __ Designed by Luhan Monat-Mesa Arizona

PIC16F84 Alarm Clock - This is an alarm clock I built.  It was very effective during the sort time I used it, because I programmed it to play a very annoying tune through a speaker.  I actualy started to wake up before the alarm went of, so other people int he house didn't wake up from the anoying pitches it played.  The Jal sourcecode is available on my download page Features * Timekeeping

PIC16F84 CW Decoder - I propose a simple CW decoder wich makes use of a PIC16F84 microprocessor with a 16x2 chars LCD display.  It is equipped with an audio frequency input from your receiver, an input for a stright key and an audio output locked to the input signal.  It automatically adapts itself to the CW rate and may be employed for learning purpose substituting the traditional tone generator and offering the capability of displaying the keyed code __ Designed by Francesco Morgantini IK3OIL
