Has been created and implemented a prototype of automatic water dispenser based on arduino eith coin selector. This system serves to assist the process of buying and selling in the market is less efficient. The system uses ultrasonic sensors, Arduino as a controller or data processor , relay circuits, LCD as a viewer module, pump gallons electric, coin selector. This machine created a prototype machine equipped with automatic water processing system uses minimum system Arduino Uno board, ultrasonic sensor for volume measurement, LCD screens to display electronic display modules, electrically gallon pump functioned as valves open / close is driven by a DC motor with a current DC, Relay which serves to move the current / voltage using large current / voltage is small, and the Coin Selector coin that serves as a sensor. After testing 10 times for each of the nominal Rp.2000 Rp.1000 and then obtained the following results, the nominal Rp.1000 takes 3,4 seconds to get water 174ml, while it takes time for Rp.2000 par 5,8 seconds to get a drink of water 298.5 ml . Compared with such transaction in general, it is more efficient because it only takes less than 1 minute to do a transaction.
