Abstract: This review paper comprehensively examines the multifaceted landscape of embedded systems, pivotal microcomputers integral to a wide range of applications, from household appliances to autonomous vehicles, characterized by dedicated functions and real-time constraints within larger mechanical or electrical systems. Embedded systems, often based on microcontrollers or microprocessors, are designed for low power consumption, small size, and cost-effectiveness, with limited processing resources that pose programming challenges. Their applications span diverse sectors, including automotive, agriculture, healthcare, and IoT, driving innovations such as advanced driver assistance systems (ADAS) which are systems that provide crucial driving support functions, crop monitoring, and smart medical diagnostics. Building upon their widespread applications, embedded systems are increasingly incorporating AI and machine learning to enhance functionality and decision-making capabilities, the integration of artificial intelligence (AI) and machine learning enhances system adaptability, enabling real-time decision-making and improved safety in autonomous vehicles and precision agriculture. Emerging trends highlight connectivity, edge computing, and IoT integration, facilitating seamless communication and data processing in smart devices like Arduino and Raspberry Pi]. However, challenges such as cybersecurity, regulatory compliance, and high computational demands persist, necessitating advanced modeling techniques and formal methods. This paper also explores educational advancements, with platforms like Arduino reshaping embedded systems to address skill demands. By synthesizing global trends, technological advancements, and future directions, this review emphasises the transformative potential of embedded systems across industries, supporting for continued innovation to overcome existing limitations. This paper aims to critically analyze the evolution of embedded systems, focusing on the integration of AI and machine learning, and the resultant challenges and opportunities.
