An accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they could be dynamic - caused by moving or vibrating the accelerometer.
Accelerometer
As the use of smart phones and mobile devices has expanded, a new type of processor has been defined. An application processors is a microprocessor optimized for smart phone / hand held device use.
Application Processors
The hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system.
Central Processing Unit
A constant is a piece of data that does not change.
Constants

Comments
A?function?(also known as a?sub-routine) is a named piece of code that can be used from elsewhere in the code. Functions such as setup and loop initializes variables, pin modes, start using libraries, and then loops code consecutively.
Functions
A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit. A microcomputer by comparison with a keyboard, monitor, and mouse are commonly referred to as a personal computer today and the prefix ?micro? is often not used anymore.
Microcomputer
A microcontroller is a small, low cost computer on a single integrated circuit.Microcontrollers are used to perform one dedicated task. One specific program. They are usually embedded in products.
Microcontroller
A microprocessor is an IC which has only the Central Processing Unit inside them. They only have processing powers.Microprocessors don?t have RAM, ROM, and other peripheral on the chip.
Microprocessor
The physical devices used to store programs or data (e.g.) on a temporary or permanent basis for use in a computer or other digital electronic device.
Memory
A program will contain: variables, functions, structures, and comments
Program
Pulse Width Modulation is a technique for getting analog results with digital means.Digital control is used to create a square wave.
Pulse Width Modulation (PWM)
A servomotor is a rotary actuator that allows for precise control of angular position, velocity and acceleration. It consists of a motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors.
Servo
A?variable?is a place for storing a piece of data. It has a type, a name, and a value. They can change.
Variables
