PIC based digital voltmeter (DVM) - This project will describe how to make a simple digital voltmeter (DVM) using a PIC16F688 microcontroller. The range of this DVM is 0-20V, but you can easily increase or decrease the range of input voltage as your requirements after you understand the voltage scaling method described in this project. The PIC micro reads the input voltage through one of the 8 analog channels and convert it to a 10-bit digital number using the internal ADC __ Contact: Raj Bhatt & Shawon Shahryiar

PIC Clock - Last summer vacation, I had an opportunity to be in dad's hobby workshop and decided to have a look at my pending projects. (I am no longer a science student but now in School of Fashion Technology for my BS Degree) I realized that I had a lot of parts in boxes that I ordered and must be utilized!! I decided to complete one more project as all that was to be done was to design a board. __ Designed by Nina Gajjar
PIC Debugging routine reads out binary numbers - 12/07/00 EDN-Design Ideas - The “burn and learn” method of firmware development excludes an in-circuit emulator and a serial port. With this method, it is common practice to use spare I/O pins on a mC as a debugging aid. By strategically placing instructions to set and clear these I/O pins in the codePDF contains multiple circuits, scroll to find this circuit Design by Brad Peeters, Theta Engineering Inc, Costa Mesa, CA
PIC Die - Built using a PIC16F84, about 4 hours worth of code and a few bits on a breadboard. This was the first time I've worked with PIC's so it was a learning exercise. I started with the 'Hello World' microcontroller equivalent i. e. Blinking LED, then tried the 'Knight Rider' sequencing LEDs, and then
PIC diode Tester - This is a simple use of the PIC 16F84 about a diode tester. __ Designed by Manolis Xenias
PIC Dual Temperature Meter - Dual PIC Temperature meter that allows to measure temperature in two different locations at the same time. Never before such a useful and powerful circuit could be built with so little components and yet provide endless possibilities. This is all possible thanks to the use of PIC16F628 microcontroller and 2x16 character LCD display that act like a small computer which can be customizable thanks to upgradeable hex firmware.
PIC Freq Meter/ Voltmeter - Measurement of the frequency up to 50MHz Measurement of power supply voltage in the range of 0.0 V, 25.5 V Measurement of the input voltage at two analog inputs, simultaneously displayed as bar graph (PWR/SWR or S) indicator. The input sensitivity could be chosen between 0.25V, 0.5V, 1.0V and 2.0V for maximum bar graph indication. This is a successor of the PIC16C71 4-digit LED f-counter & V-meter.

PIC In-Circuit Programming Add-on - Does your PIC programmer have provision for in-circuit programming? Some such as Microchip's PICSTART Plus don't but you can add this useful function to your programmer by building a simple adaptor!__ SiliconChip
PIC IR/ RF Remote Control - This is a general purpose remote control project with using programmable PIC microcontrollers (PIC16F628, PIC16F630, PIC16F684) . Schematics are shown for using infrared (IR) or radio (RF) media. If you are not familiar with microcontroller programming, you can use fixed encoder and decoder integrated circuits instead. Well-known such IC-s are Holtek HT-12D, HT-12E and Motorola MC145026, MC145027, MC145028.
PIC Logic Probe with Pulser - This project is a combinationLogic Probe and Logic Pulser. It is capable of testing all sorts of digital and microcomputer projects. You will find it extremely handy when designing a project as the golden rule is totest everything in steps and stages during the design-and-construction process. If you are not sure how a Logic Probe or Pulser works __ Designed by Prepared Colin Mitchell
PIC Micro LED Projects - Here is a neat PIC Project that I created using the 16F84 chip and a neat little bi-color LED from Radio Shack. The LED can be red or green depending on the bias of the diode. By using two of the PORT B pins, I can control the bias of the LED. If the LED is on PORT B, Pin 0 and Pin 1, I can set Pin 0 HIGH and Pin 1 LOW, this would make __ Designed by Jason KE4NYV from Roanoke, Virginia
PIC Micro Multiple Servo Motor Interface - Using a modified version of the last program, we can control as many servomotors as we have I/O lines on port B. In the next listing, we will control two servos in the same manner as we controlled a single servo in the previous program. The circuit is shown in figure 4 (below) .

Embedded control products are found in all market segments: consumer, commercial, PC peripherals, telecommunications (including personal telecom products) , automotive and industrial. Most embedded control products must meet special requirements: cost effectiveness, low-power, small-footprint and a high level of system integration. __ Designed by YO5OFH, Csaba Gajdos
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 and has a relay as an output switch. It should also sense if the connected «consumer» is turned-on or off and report to the administrator at the other end of the phone line. The administrator would then call-in the device, log in with the password, and check the state of «consumer», turn it on or off, change password or some other settings.
