![]() ![]() ![]() ![]() Servo servo // Declare an object for servo motor #include //Include Library for Servo Motor Two variables are also declared so that the value of the distance and time of the ultrasonic signal can be saved and then used in the formula. An object is also made so that it can be used to set values for the servo motors. Two pins of the Arduino Nano board are also initialized so that they can be used for the trigger and echo pin of the ultrasonic sensor. ![]() At the start, a library is included so that we can use built-in functions to operate the servo motor. The code is pretty well commented but still, it is briefly explained below.ġ. Click on the upload button to burn the code on your microcontroller board. Download the code attached below and paste it into your Arduino IDE.To include the library, click on Sketch > Include Library > Add ZIP. This library is attached along with the code, in the link below. To write code to operate the servo motors, we need special library that will help us to write several functions for servo motors.In the same Tool menu, Set the Processor to ATmega328P (Old Bootloader).In the same Tool menu, set the port to the port number that you observed before in the Devices and Printers.and set the board to Arduino Nano from the drop-down menu. In my case it is COM14 but it is different on different computers. Now click on Devices and Printers. Here, find the port to which your microcontroller board is connected. in the control panel, click on Hardware and Sound. Connect your Arduino Nano board to your laptop and open the control panel.Download the latest version of Arduino IDE from Arduino.If you are not already familiar with the Arduino IDE, don’t worry because a step by step procedure to set-up and use Arduino IDE with a microcontroller board is explained below. This motor is coupled to a sensor which is sending feedback about its motion. These motors allow the precise control of angular or rotatory motion. These motors are different from DC motors. Ultrasonic Sensor.Ī Servo Motor is a rotatory or a linear actuator which can be controlled and moved in exact increment. The distance is calculated by using the time, that ultrasonic signal takes to go from the transmitter and come back to the receiver. When the transmitter sends an ultrasonic wave, it reflects after colliding with a certain object. The transmitter converts the electrical signal into an ultrasonic signal and the receiver converts the ultrasonic signal back to the electrical signal. It consists of a transmitter and a receiver. HC-SR04 board is an ultrasonic sensor which is used to determine the distance between two objects. The microcontroller on the Arduino Nano board is ATmega328p. if you don’t have an Arduino Nano, you can also use Arduino Uno or Arduino Maga. Arduino Nano has exactly the same functionality as Arduino Uno but in quite a small size. We burn a C Code on Arduino Nano to tell the microcontroller board how and what operations to perform. Now, as we have a complete list of all the components, let us move one step forward and go through a brief study of the working of every component.Īrduino Nano is a breadboard-friendly microcontroller board that is used to control or carry out different tasks in a circuit. ![]()
