Aim:
To identify, observe, and understand the applications of different actuators.

Requirements:

• Arduino or Raspberry Pi Pico

• Small DC motor

• Servo motor

• Piezo buzzer

• Relay module (optional)

• Jumperxxxxxxx wires

Procedure

1. Arrange the Components
   • Place all actuators on a table for easy observation.

2. Observe Physical Features
   • Look for size, shape, and moving parts in each actuator.

   • For example: Servo motors have a small rotating arm, DC motors have a spinning shaft.

3. Watch Demos or Run Simple Tests
   • Connect each actuator to the Arduino/Pico (or watch a short video demonstration).

   • Make the DC motor spin, move the servo to different angles, or beep the buzzer.

4. Identify Their Applications
   • Discuss where each actuator might be used:
     • Servo → camera movement

     • DC motor → toy car wheels

     • Buzzer → alarm system

     • Relay → turning on a fan remotely

5. Record Your Observations
   Note the motion type, speed, precision, and possible uses for each actuator.
