A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. wikipedia.org

An embedded system is a computer system designed for specific control functions within a larger system. often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. wikipedia.org

Arduino is a popular open-source single-board microcontroller, descendant of the open-source Wiring platform, designed to make the process of using electronics in multidisciplinary projects more accessible. wikipedia.org

A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. wikipedia.org

Altium Designer is an EDA software package for printed circuit board, FPGA and embedded software design, and associated library and release management automation. It is developed and marketed by Altium Limited of Australia. wikipedia.org

Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. wikipedia.org

Integrated circuit design, or IC design, is a subset of electrical engineering and computer engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs. wikipedia.org

Analogue electronics (or analog in American English) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two different levels. wikipedia.org

The internet of things (IoT) is the network of physical devices, vehicles, buildings and other items. It is embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data. wikipedia.org

Digital electronics, or digital (electronic) circuits, represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state. wikipedia.org

Java is a programming language and a core component of Oracle Corporation's Java Platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. wikipedia.org

C (pronounced like the letter C) is a general-purpose computer programming language developed between 1969 and 1973 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system. wikipedia.org
