ARDUINO UNO

  Servo motor configuration: Connect the Signal pin of the Servo motor to  the vacant PWM pin of the Arduino. Connect the VCC of the servo motor to the 5V pin. Connect the GND of the servo motor to the GND. Import the header file to the Arduino code. Compile and upload the code to the Arduino Uno R3.

  What are the benefits of using servo motor? Advantages of Servo Motors High efficiency. High output power relative to their size. More constant torque at higher speed. Closed-loop control. Quiet operation. Highly reliable. High ratio of torque to inertia. High acceleration

Servo motor        A servo motor is a rotational or translational motor to which power is supplied by a servo amplifier and serves to apply torque or force to a mechanical system, such as an actuator or brake. Servo motors allow for precise control in terms of angular position, acceleration, and velocity.

  PIR connections - Connect the Gnd pin   sensor to the ground of Arduino. Vcc pin of the sensor to 5V of Arduino. And signal / output pin to digital pin 5 of Arduino board. Led connections -  Positive terminal of the led to digital pin 9 of Arduino.

What is the PIR sensor? A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

  Arduino – Ultrasonic Sensor Connect the +5V pin to +5v on your Arduino board. Connect Trigger to digital pin 7 on your Arduino board. Connect Echo to digital pin 6 on your Arduino board. Connect GND with GND on Arduino

  Ultrasonic sensor  What is an Ultrasonic Sensor?  An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object's proximity.

  What is Arduino Uno used for?     Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into a variety of electronic projects. This board can be interfaced with other Arduino boards, Arduino shields, Raspberry Pi boards and can control relays, LEDs, servos, and motors as an output.

   The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010.[2][3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits.[1] The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable.[4] It can be powered by a USB cable or a barrel connector that accepts voltages between 7 and 20 volts, such as a rectangular 9-volt battery. It has the same microcontroller as the Arduino Nano board, and the same headers as the Leonardo board.[5][6] The hardware reference design is distributed under a Creative Commons Attribution Share-Alike 2.5 license and is available on the Arduino website.
