Servo Motor Projects

Maximize solar panel energy harvest with an intelligent single-axis sun tracker that pivots toward the brightest light source in real time.

Build a smart parking lot gate with entry and exit ultrasonic sensors, a servo barrier arm, green and red traffic lights, an audio chime, and live slot tracking on an LCD.

Build a hygienic touchless trash bin using an Arduino Uno, an HC-SR04 ultrasonic sensor, and an SG90 micro servo that automatically opens when your hand approaches.

Build a servo angle positioning dial with the Raspberry Pi Pico. Map analog potentiometer readings into 50Hz PWM pulse widths to command an SG90 micro servo from 0° to 180° with endstop boundary alerts.

Build a two-axis camera mount or pointer using an Arduino Mega, an analog thumb joystick, and two micro servos. Move the joystick to turn left, right, up, and down in real time.

Turn an analog potentiometer knob to steer an SG90 micro servo smoothly from 0 to 180 degrees using an ESP32-C3. Learn how 12-bit analog converters read physical dial positions and generate precision 50Hz motor pulses.

Turn an analog knob to steer an SG90 servo motor smoothly from 0 to 180 degrees. Learn how microcontrollers read knob angles and generate precision timing pulses without external libraries.

Connect a servo motor and a push button to your Arduino. Each press toggles the lock between open (0°) and closed (90°). This project introduces the most important thing a servo can do: move to a specific angle and stay there.

Protect valuables with a secure digital safe featuring a 4x4 matrix keypad, LCD1602 feedback, buzzer alerts, and an SG90 servo deadbolt mechanism.

Control a two-axis robotic turret using dual SG90 servos and an analog thumb joystick with smooth deadband filtering and real-time degree feedback on an LCD1602.

Build an automated greenhouse climate controller using a DHT22 sensor, I2C LCD1602 display, simulated cooling ventilation fan, and heating elements.
