Whether you are an engineer or a businessman, a microcontroller plays a pivotal role in running your devices properly. Let's have a quick guide on microcontrollers, including their features, types, and applications.  

What is a Microcontroller? 

A microcontroller is a reliable and effective integrated circuit (IC) that combines a processor core, input/output chips, and memory, all assembled in a single chip. Compared to a microprocessor, which requires RAM and ROM to process the operation, microcontrollers do not require these and combine the components in a single chip, making it cost-effective and efficient in handling various appliances.  

What Are The Major Components Of A Microcontroller?  

A typical microcontroller consists of: 

• Random Access Memory 
• Input/Output (I/O) Ports 
• Timers and Counters
