Car garage project

The device relies on a distance sensor installed in parking lots, which detects the car. When it approaches the gate, the distance sensor sends a signal to the Arduino to give a command to the servo motor to open the gate. Arduino Uno R3 with connecting wire. Arduino Uno: 1 piece. Ultrasonic distance sensor: 1 piece. Male-to-male connecting wires, 15 pieces. 20 cm length. Experiment allowance: 170 points. White color. SG90 servo motor. Explanation video.
