Aim:
To use Arduino or Raspberry Pi Pico to rotate a servo motor when a button is pressed.

Requirements:

• Arduino or Raspberry Pi Pico

• Servo motor

• Push button

• Breadboard & jumper wires

• Arduino IDE (for Arduino) or Thonny (for Pico)

Procedure:

1. Circuit Connections
   • Connect the servo motor’s signal pin to pin 9 (Arduino) or GP15 (Pico).

   • Connect the servo’s VCC to 5V (Arduino) or 3.3V (Pico).

   • Connect the servo’s GND to the microcontroller’s ground.

2. Button Setup
   • Place the push button on the breadboard.

   • Connect one side of the button to 5V (Arduino) or 3.3V (Pico).

   • Connect the other side to a digital pin through a pull-down resistor to ground (ensures the button reads LOW when not pressed).

3. Upload the Code
   • Write a program that:
     • Reads the button state (pressed or not pressed).

     • If pressed → rotate servo from 0° to 90°.

     • If not pressed → move servo back to 0°.

4. Test the System
   • Press the button and observe the servo movement.
   • Release the button and check if it returns to its original position.
