Servo Motor Usage
Basic usage project that positions the servo motor to 0°, 90° and 180° angles in sequence. Teaches servo library and angle control logic.
Servo Motor Operation with Potentiometer
Project that controls the servo motor in real time by converting the potentiometer value to the range 0-180°. teaches map() function and analog-servo integration.
Servo Control with Joystick
Pan-tilt project that independently controls two servo motors in X and Y axes with joystick module. Teaches the logic of joystick-servo integration and position tracking.
4x4 Keypad LCD Display Password App
Security project that opens the door with servo if it is correct by entering a password with a 4x4 keypad and turns on a red LED if it is wrong. Teaches password comparison and servo-LCD-keypad integr
Obstacle Avoidance Robot
How about building a smart vehicle that finds its own way? The Obstacle Avoidance Robot constantly scans its surroundings thanks to the ultrasonic sensor in front of it. When it encounters an obstacle
Smart Electronic Safe
Smart Electronic Safe is an Arduino based password protected security system. It opens and closes the servo motor controlled lock mechanism with a 4-digit password entered via the 4x4 keypad and trans
SG90 Servo Angle Control with Pot
Servo Motor (SG90) Control with Potentiometer The main objective of this project is to precisely control the angular position of a servo motor in real time using an analog input unit, the potentiometer. The project is a basic engineering example to grasp the logic of analog-to-digital conversion (ADC) and signal mapping. Operation Logic: Analog Data Reading: When the user turns the potentiometer, the resistance change results in a voltage signal between 0V and 5V on the A0 analog pin of the Ard
Servo Circle Choreography - Animated Patterns with 32 Servos
A visual animation project using 32 servo motors arranged in a circle on an Arduino Mega. The servos are managed in a single array, connected to Mega's pins 22-53, and exhibit four different motion sequences: a chaotic vibration where all servos move at random angles, a synchronous sweep where they all move at the same time, a smoothly rotating wave around a circle, and finally a compass needle swinging left and right. The swirling wave effect is created by the rotation of each servo relative to
ESP32 Servo Motor (Potentiometer Control)
In this project, we control an SG90 servo motor using a potentiometer. We adjust the servo angle by mapping the analog value read from the potentiometer to the 0–180-degree range. Thanks to the ESP32Servo library, any GPIO pin on the ESP32 can generate a PWM signal. This is a fundamental control method for robotic arms, camera gimbals, and automatic door mechanisms.
ESP32 RFID Door Lock (RC522 + Servo + OLED + Buzzer + LED)
We’re building a smart door lock using an ESP32, an RC522 RFID module, an SG90 servo motor, an SSD1306 OLED display, an active buzzer, and 2 LEDs. When a card is scanned, its UID is compared to the list of authorized cards stored in the code—if authorized, the servo motor rotates to unlock the door (green LED + 2 short beeps), and the door automatically locks again after 5 seconds. For an unauthorized card, the red LED lights up, a warning is given with 3 rapid beeps, and the captured UID is dis
