Voltmeter Ammeter Kit – Blue Backlight LCD

Voltmeter Ammeter is a great kit to measure voltage and current at the same time. It measures 0-70V or 0-500V voltage with 100mV resolution and current from 0 to 10A. It's a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. Kit uses PIC16F876A microcontroller with built-in ADC (Analog to Digital Converter) to sample voltage with ...

Build your own “2-Wire LCD Interface” using the PIC16C84 microcontroller

2-Wire LCD Interface for the PICMicro Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much more "professional" and easy to use. I like to use LCD's to help debug applications, with breakpoints set to display ...

0-5V LCD volt meter using PIC16F877A

This PIC LCD volt meter project uses a PIC micro and an HD44870 LCD display. The analogue input is taken directly to the analogue input pin of the microcontroller without any other processing. So the input range is from 0V to 5V - the maximum source impedance is 2k5 (for testing use a 1k pot). To improve the circuit add an opamp in front to present greater impedance to the circuit under test. The output imp ...

Simple Digital GPS Speedometer Using PIC16F877A with LCD Display

Speedometer is a speed measuring gauge used to calculate the speed of motor vehicles. They are mainly of two types- electronics and mechanical. Digital speedometer measures the speed and mileage in vehicles. Normally both types work on the principle of electromagnetism, however they have a disadvantage that they cannot be used if there are no wheels on the moving object. Here I am introducing a simple digit ...

3310 Nokia LCD & PIC12F683

Not long ago I saw this link for a 3310 temp probe. Now ive played with other LCD’s lots, but this one caught my attention because of the low power requirements (It runs from a single CR2032 Motherboard battery). I built the Temp probe as shown on the site and it worked well. I had several of the PCBs made, and decided that the others would be my own projects with the same hardware. I wondered what I could ...

How to choose a MicroController using PIC16C84 microcontroller

How to choose a MicroController It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips. But times have changed. Digikey lists over 16000 different line items under a 'microcontroller' search. Which one should a h ...
