It was brought to my attention that some newbies may stumble in and, as some posts can be quite technical, it would help to have a glossary. So, presented below is a short list of terms that you may find used extensively throughout the site.
Arduino: An open source single-board microcontroller.
Raspberry Pi: A credit card-sized single-board computer running ARM architecture processors.
ARM: A family of instruction set architectures for computer processors based on a reduced instruction set computing (RISC) architecture. Many smartphones use these processors.
Capacitor: A component which has the ability or “capacity” to store energy in the form of an electrical charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable battery. Rated in farads.
LiPo: Lithium Polymer battery. A rechargeable battery of lithium-ion technology in a pouch format. Unlike cylindrical and prismatic cells, LiPos come in a soft package or pouch, which makes them lighter but also lack rigidity.
Resistor: A passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits.
LED: Light-Emitting Diode.
Diode: A a two-terminal electronic component with asymmetric conductance; it has low (ideally zero) resistance to current in one direction, and high (ideally infinite) resistance in the other.
Microcontroller: A small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.
ATmega: A series of microcontroller chips developed by Atmel.
