The purpose of an embedded system is to control a particular device, a larger system or process. Embedded systems responsibilities include design, development, and managing embedded systems for products. There are various forms of embedded systems including standalone embedded systems, network embedded systems, mobile embedded systems and Real-time embedded systems. The embedded systems comprise three primary components including application-specific software, real-time operating systems (RTOS) and hardware

Embedded systems engineering can be simple or complex. We will start with an LED (Light Emitting Diode) to help you understand the concept of embedded systems engineering. The image below shows a simple embedded system consisting of an Arduino powering a red LED.

An example of a simple embedded system (Embedded LED System)

Embedded systems engineering is prevalent but not many people know they are using these systems. Have you ever walked into a room and the lights automatically turned on, or you stood in front of a door that opened without needing to open it using the door handle? 

The embedded system combines both computer software and hardware designs to carry out a specific task. Embedded systems can function within larger systems such as consumer electronics, agricultural and processing industrial devices, automobiles, industrial machines, medical equipment, household appliances, vending machines, mobile devices and toys

It is important to appreciate that the embedded systems engineering future is bright as technology advances continue as more and more systems continue to be automated. The pandemic taught us that having systems in place that eliminate the need for human interaction can play a critical role in saving lives. For instance, If a door can open without contact this can be instrumental in preventing the transfer of contaminants such as viruses and bacteria thus preventing the spread of disease which in turn would prevent another pandemic from taking place.

Embedded Systems and the Future

Embedded systems are all around from microwaving to brewing coffee, and even getting to the office using an elevator. Various components make up embedded systems these comprise of the sensors that are used in capturing the input signals. Therefore, it is important to take into consideration embedded systems and the future.
