Microcontroller vs Microprocessor

The term microprocessor and microcontroller can be confusing for those who are new to this field. I recommend you to read our articles What is a Microcontroller ? and What is a Microprocessor ? to understand more about microcontroller and microprocessor. Both microcontroller and microprocessor are programmable multipurpose silicon chip, clock driven, register based, accepts binary data as input and provides output after processing it as per the instructions stored in the memory. Let's see the key differences between them. Intel...

Digital Alarm Clock using PIC Microcontroller and DS3234 RTC

Here is a digital alarm clock made using PIC 18F4520 Microcontroller and DS3234 RTC (Real Time Clock). This project is for educational purposes or can be used as a reference for integrating DS3234 RTC. DS3234 is a very accurate RTC IC with integrated on chip temperature compensated crystal oscillator. It can be integrated with a microcontroller using SPI bus. This project is developed using MPLAB XC8 compiler.

What is a Microcontroller ?

A microcontroller is an integrated circuit (IC) which is small, low cost and self contained computer designed to handle a specific task in embedded systems. In simple words, a microcontroller (MCU or Microcontroller Unit) is a small computer integrated in to a single chip. We can also explain it as programmable silicon chip which is clock driven, register based, accepts input and provides output after processing it as per the instructions stored in the memory. A computer is a...
