Practical tools that follow developments are needed. One of the practice modules in the control laboratory is the automatic gate opening and closing system. An automatic gate opening and closing system is made to increase convenience and security. Currently, a practical simulation tool for an automatic gate open and close control system based on the Arduino Uno R3 Atmega 328p microprocessor is made. The process of opening and closing this gate uses the FPM10A fingerprint sensor with the addition of the HC-SR04 ultrasonic sensor and programming the time to close automatically. Fingerprints are used to control the opening and closing of the gate. Ultrasound is used so that the gate does not hit an object that is blocking the gate closing process. Time control is used for the process of closing the gate automatically if the owner forgets to close the gate when the door is left. The designed gate simulation tool has a size of 1000 x 600 mm. With a track length of 2000 mm. The electric motor used is 12-24 Volt DC with a rotation of 150-200 rpm. The control system uses the Aruino Uno R3 microcontroller with operating specifications of 5 DC Volts, Current of 20 mAmpere. The test results show that the tool can function properly. The solenoid for the lock works fine. Gate opening speed 8.2 seconds. Closing speed 8.17 seconds. The distance between the door and the obstacle object will reopen 10 cm. Gate closes automatically when left after 60 seconds. Implemented systems and test data show that all security components/features operate successfully. The test results show that the prototype is running well.
