Laboratory experiences are the part of science and technology curricula of higher education. This laboratory manual intended to support the undergraduate and postgraduate students in the related fields of Electronics for practicing embedded system experiments. The chapters begin with an introduction, and it covers the experiments for the 8085 Microprocessor & 8051 Microcontroller laboratory. Each experiment consists of aim, hardware/software requirements, algorithm, program, experimental results, and conclusion. For the most part, the lab manual includes the standard laboratory experiments that have been used by many academicians related to electronics departments for years. Over sixty-three practical experiments described here to explore the practical knowledge of students on embedded systems. This book comprises two chapters that are focused on the lab experiments of the 8085 Microprocessor & 8051 Microcontroller laboratory.This book helps to -Promote experiential learning among the students-Give practical or informal knowledge to understand how things work-Know the interaction between software and hardware
