Universal asynchronous receiver transmitter Wikipedia. A universal asynchronous receiver transmitter UART is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable. The electric signaling levels and methods are handled by a driver circuit.

While the software of mikrokontroler using language of assembly. This system work after pressing the keypad of room at master control for the election of gone to room and master will ask an answer at system slave. Slave system will give an answer by pressing the keypad than delivered to master control by serially and presented to LCD. This System can present article at LCD and also accept of choice answer at each slave which in the form of 4 indicator lamp with each indicator have an own answer sentence.
