Although the PIC 16F84A is really obsolete and I wouldn’t normally do a project using it, this chip is used extensively throughout education and for many people. PIC16F84A Projects. A collection of PIC16F84A 8-bit MCU projects with different types of compilers. Circuit diagrams and source codes are included.

Setting a bit in the TRIS register to zero sets the pin direction to an output. Proteus Design Suit for virtual circuit design.

The input voltage can go up to 35V without damaging the although the power dissipated by the will increase for higher input voltages i.

Best Internet of Things final year projects The Internet of Things was a revolutionary trend that altered the course of technology in a massive way. Third and fourth buttons are used to choose direction rotation of the motor direction 1 or projrcts 2.

In the UK you can buy a suitable power supply from Rapid Electronics.

We can calculate the range through the time interval between sending trigger signal and receiving echo signal. The compiler is free for the small amounts of code used here. You should check part and descriptions are correct when ordering in case I’ve made a mistake transferring them onto this page. Very useful, prijects, honest and clear.


This simple circuit functions as a 12 LED chaser. Here are its features and a short comparison. The PIC16F84 is a the most well known and most well used of all the PIC microcontrollers – it is used in numerous projects that you can find across the web.

The asm ;rojects are the source code which you can modify or just view to see how it works.

PIC16F84 Introduction

Subscribe To Our Newsletter. The program that runs on this chip controls the LEDs attached to the output port pins.

The push buttons control the LED blinking. The following code flashes the LED. As of microchip are recommending that you use 16F84A instead of 16F84 with the only difference being that the A-version runs at 20MHz using a 20MHz crystal the non-A 16t84a runs at 10MHz crystal speed only. The LCD is used to display the time as well as the date.

The circuit has been constructed on a PCB but can easily be built on strip-board, or 1f684a solderless breadboard.

This small chip can count seconds, minutes, hours, day, date, month and year with leap-year up to year The LED current limiter resistor 1k is not ideal it just lets you see the led you don’t need maximum current to see it – Replace the 1k with a if you want brighter output. The DS receives and transfers data clock data and calendar data as BCD format, so after receiving data we have to convert these data into decimal data, and before writing data to the DS we have to convert this data from decimal to BCD format.


You can unsubscribe at any time. The sensor provides fully calibrated digital outputs for the two measurements.

Even though the 16F84 is getting on a bit, it is one of the most popular of the PIC microcontrollers and there are hundreds of circuits for it on the web but it does have limited memory, RAM and peripherals See diagram below. It is best to use the 5V power supply circuit as it not only correctly regulates the dc voltage but it protects your PIC chip. It is an 8 bit mid-range microcontroller having words of program memory, 68 bytes of RAM and 64 bytes of long term EEPROM storage and a single peripheral – an 8 bit timer – Timer0.

Proton pic programming for beginners with a nice supply of protons are prepared with a lot of practice.

A single control bit can turn on all the pull-ups. The circuit is clear and simple. The last button stops the motor no matter what speed or direction.
