Batteries are the most common power source for basic handheld devices to large scale industrial applications. A battery can be defined as; it is a combination of one or more electrochemical cells that are capable of converting stored chemical energy into electrical energy.
A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric resonator, a crystal, as its frequency-determining element. Crystal is the common term
An electronic circuit formed on a small piece of semiconducting material, which performs the same function as a larger circuit made from discrete components
A microcontroller is a small computer on a single metal-oxide-semiconductor integrated circuit chip. A microcontroller contains one or more CPUs along with memory and programmable input/output peripherals.
A buzzer is a audio signaling device, which may be mechanical, electromechanical or piezoelectric. Buzzers are typically used for alarm devices, timers ect.
A diode is a two-terminal electronic component that conducts current primarily in one direction
A liquid-crystal display is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
A capacitor is a passive electronic component with two terminals.
An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil
A light-emitting diode is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.
A switch device for making and breaking the connection in an electric circuit.
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
