Digital Voltmeter (0-50v) using PIC Microcontroller

If we know how inbuilt ADC work then we can easily build Digital Voltmeter using PIC Microcontroller. In my previous post, we can see how easily we build “Digital thermometer with auto saving log file in excel by Pic microcontroller”. Using the same principle here we build Digital Voltmeter using PIC Microcontroller. Requirement: To make digital voltmeter we uses some material here I give you the list of th ...

DATA LOGGER measures and stores voltage using PIC16F876

Introduction This circuit is a data logger that records voltage samples at specific time intervals. I've used it to record the voltage discharge curve on NiCad battery packs. The data file can be dropped into a spreadsheet and plotted. I've also used it to record the amount of time a possibly defective refrigeration unit was running during a 24-hour period (using a current clamp and full wave bridge.) Featu ...

Digital Watt meter using PIC16F876

Updated 3. Sep. 2002. If you are from Denmark ! read the Danish version !! In the good old days I had some parts but now This Wattmeter is in ELEKTOR MAGAZINE OKTOBER 2002, they will sell PIC and PCB The extra input B is for a later SWR brigde project, also the TX serial output will be in use later. The uncalibrated signal response is: +1/-1 dB from 1MHz to 450MHz. Input SWR vill varry from 1.00 to 1.30, de ...

50MHz 7 segment frequency counter using PIC16F877A

In the same way as the LCD project this frequency counter circuit uses TMR1 in 16 bit counter mode to count the input signal edges. Counter overflows are accumulated to give the total count in multiples of 65536. Adding the current value of the counter at the end gives the total count. Specification of the frequency counter circuit Min frequency 1Hz Max frequency ~50MHz (limited by input pin characteristics ...

Frequency Counter using PIC16F877A Microcontroller

This PIC frequency counter project uses an LCD to display the frequency and PIC timer 1 (TMR1) to measure the input signal. It uses TMR1 in 16 bit counter mode to count the input signal edges and overflows of the counter are accumulated to give the total count in multiples of 65536. Adding the current value of the counter at the end gives the total count. Since the measurement time is 1 second the final cou ...

Function Generator using PIC16F870 microcontroller

Sine Triangle Square Saw Burst Sweep Noise - runs on a PIC16F870 After the recent demise of our multifunction signal generator, we decided to make one of our own.   The circuit uses a PIC16F870 (about $3), an R/2R resistor ladder network (for a real fast and cheap D/A),  and a few other parts. You can check out the schematic and the current source file.  Also the object (hex) file.  All of the sine wave fun ...

LC meter using PIC16F628A Microcontroller

I needed a good LC meter for my one of my next projects so I went and built the famous LC meter by Phil Rice. This LC meter design is pretty old but since it is a perfectly good device there was no need to design/build/debug one of my own. So, I just changed the original firmware a bit and added few electronic goodies to it to make it more compact. UPDATE: Project is on HackedGadgets, ...and now also on Hac ...
