PIC16F877A-Based Temperature Monitoring System

Temperature monitoring and control is important in industry environments. Sensors are widely used for measurement of temperature. Usually, a temperature sensor converts the temperature into an equivalent voltage output. IC LM35 is such a sensor. Here we describe a simple temperature measurement and display system based on LM35 sensor and PIC16F877A microcontroller. The temperature in degrees Celsius is disp ...

Mars Clock using PIC16F877A microcontroller

What do you do if you have a spare LCD module with backlight, a weird 16 button keyboard, and a PIC16F877A microcontroller gathering dust? A monster Martian Clock immediately springs to mind. You are probably thinking "There are hundreds of PIC clocks on the Net - do we need yet another one?!" Well, this one is a bit different: It has 16 timers that can be independently paused and restarted, and can run for ...

Understanding Timers in PIC Microcontroller with LED Blinking Sequence

This will be the fifth tutorial in our PIC Tutorial Series, which will help you to learn and use Timers in PIC16F877A. In our previous tutorials, we had started with Introduction to PIC and MPLABX IDE, then we wrote our first PIC program to blink the LED using PIC and then made a LED Blinking Sequence by using delay function in PIC Microcontroller. Now let us use the same LED Blinking sequence which we have ...

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 ...
