A '''single-board microcontroller''' is a [[microcontroller]] built onto a single [[printed circuit board]]. This board provides all of the circuitry necessary for a useful control task: a [[microprocessor]], [[input/output|I/O circuits]], a [[clock generator]], [[RAM]], stored program memory and any necessary support [[integrated circuit|IC]]s. The intention is that the board is immediately useful to an application developer, without requiring them to spend time and effort to develop controller hardware.

}}</ref> This EPROM was then physically plugged into the board. As the EPROM would be removed and replaced many times during program development, it was common to provide a [[Zero Insertion Force|ZIF]] socket to avoid wear or damage. Erasing an EPROM with a [[ultraviolet|UV]] eraser takes a considerable time, and so it was also common for a developer to have several EPROMs in circulation at any one time.

Some microcontroller devices were available with on-board EPROM. These would also be programmed in a separate burner, then put into a socket on the target system.

Line 108 ⟶ 107:

The original market demand for a simplified board implementation is no longer as relevant for microcontrollers. Single-board microcontrollers are still important, but have shifted their focus to:

* Easily accessible platforms aimed at traditionally "non-programmer" groups, such as artists, designers, hobbyists, and others interested in creating interactive objects or environments.<ref>[http://www.arduino.cc/ Arduino's home page]</ref> Some typical projects in 2011 included: the backup control of DMX stage lights and special effects, multi-camera control, autonomous fighting robots, controlling bluetooth projects from a computer or smart phone,<ref name="Dwengo" /> LEDs and multiplexing, displays, audio, motors, mechanics, and power control.<ref>Arduino [http://arduino.cc/forum/ User's forum]</ref> These controllers may be embedded to form part of a [[physical computing]] project.
