This tag is related to questions that have something to do with microcontrollers in general. A microcontroller is a simple or small processor often with its program and execution memory on the same chip with input/output pins for controlling other hardware. Microcontroller programs are embedded programs often talking directly to hardware registers without using an operating system. Microcontrollers are generally resource limited, program space measured in bytes, kilobytes or megabytes, processor clock speeds often in the kHz and tens of MHz range.
