In this paper, the automatic gas valve control system is designed using arduino hardware. Arduino is an open hardware platform that provides a rapid prototype development. A servomotor is fitted to a gas valve. Four control positions are carried out by the module, two main positions are used to open or close the valve. The valve opens at 90 relojes de imitacion suizos españa and closes to 0. This library allows an Arduino board to control RC (hobby) servo motors. Servos have integrated gears and a shaft that can be precisely controlled.
