This essentially turns the servo into a geared DC motor with position control disabled. The below circuit diagram shows how a arduino servo motor control can be done using a potentiometer. Connect the ...

Use the Arduino code given below to program your Arduino and connect all the Servo Motors as shown in the circuit diagram with proper power supply to Motors. Therefore, all servos will work together ...

Components Required: Arduino Uno RFID Reader (RC522) Servo Motor (SG90 or similar) 16x2 LCD (I2C or parallel interface) 3 LEDs (Red, Yellow, Green) Piezo Buzzer (2 pins) Resistors (220Ω for LEDs) ...

Connect the SDA, SCK, MOSI, MISO pins of the RFID reader to the digital pins 10, 13, 11, and 12 of the Arduino board, respectively. Connect the VCC and GND pins of the servo motor to the 5V and GND ...

Then convert the RFID UUID number to a string and check whether it matches with the correct UUID number. If yes, then the servo motor automatically gets activated for unlocking the door. Power the ...
