How to Change the Size of Sprite According to the Loudness

Hello guys. In this blog we are going to see about changing sprite size according to the loudness input given to the microphone 

Coding with Blocks

1) Lets place "when flag clicked" Block from "Events panel". The "when flag clicked" Block triggers the Blocks/Block code connected to it below.



2) Now lets place "forever" Block from "Control" panel. The Blocks/Block inside the "forever" Block
will run continuously. 



3) Now lets place "set size to _" Block from "Looks". The "set size to _" Block sets the size of sprite for giving value, here cat is the sprite. Play around by changing the value of it's size.

Note - "forever" is used here to change the value of "set size to_" Block continuously. It will be needed in 4th step and 5th step.



4) Now drag and drop "_*_" Block inside "set size to _" value area from "Operators" panel. It multiplies two values from each side.  



5) Now drag and drop "loudness" Block inside  the value area from "Sensing" panel. This Block gets value (0% - 100%) loudness value form microphone. After placing "loudness". Type value 2 to the remaining empty area in a multiplication operation (To check value of the loudness value in the corner, tick the loudness option)  



Run your scratch code

To run your code, click the flag button (right side of your code), Shout little bit to change of your size of the sprite😁

THE SG90 SERVO MOTOR WITH AN ARDUINO

By -
Image
Hi guys, today, I will show you how to use a servo motor with an Arduino. This tutorial is ideal for beginners because it is easy and it gives them the foundation to build interesting projects like robots for which servos are commonly used. Servo motors are high torque motors which are commonly used in robotics and several other applications due to the fact that it’s easy to control their rotation. Servo motors have a geared output shaft which can be electrically controlled to turn one (1) degree at a time. For the sake of control, unlike normal DC motors, servo motors usually have an additional pin asides the two power pins ( Vcc and GND ) which is the signal pin. The signal pin is used to control the servo motor, turning its shaft to any desired angle. For this tutorial, we will be using the popular SG90 servo motor and our goal will be to rotate the servo motor from one end to the other. Servo’s have high current requirement so when using more than one servo motor with the Arduino,

www.channelswimmingdover.org.uk      Kumar anadan was born on 1943 in Valvettithurai, Jaffna. He was graduated in University of London. He obtained Bachelor of Laws degree in Sri Lanka. He was an Attorney at Law by profession.       He was a holder of Guinness Worlds Records and he has many records. One of the famous records is Swimming the Palk strait from Sri Lanka to India and comes back within 51 hours, in the year 1971. These are some other records Non-Stop water treading for 80 hours at Chennai, Standing with one leg for 33 hours, Non-Stop dancing, Ball punching for 136 hours, etc. So, people were called him as “Aalikumaran Anaden” .       Once he met with a motor vehicle and hospitalized for 6 months. He died on 6 August 1984 while he attempting to swim the English Channel during collapse.

      A whole man is made by reading. because, it’s provided many information and experience for us from all over the world. And improve our language and creativity also. How exercise maintain our body heathy as well as reading maintain our mind healthy.       Julius Caesar said that if there any man who reads 1000 books, he is my guide. “I did not want freedom if there any books in prison” said Nelson Mandela. Albert Einstein said “ human best invention is book”.The news reporter ask "If you are gone alone, what will you do?" Jawaharlal Nehru said that he would live happy with books. So, famous people who are disappear from world, gained victory through reading books.       Finally, we can say that reading is very important and a most valuable thing over the world.

How to Draw a Rectangle using Pygame

By -
Image
What is Pygame? Pygame is a Python library designed to develop video games. Pygame adds functionality on top of the excellent SDL library. This allows you to create fully featured games and multimedia programs in the Python language. The Functions We Need! pygame.display.set_mode() : This function is used to initialize a surface for display. This function takes the size of the display as a parameter. pygame.display.flip() : This function is used to update the content of the entire display surface of the screen. pygame.draw.rect() : This function is used to draw a rectangle. It takes the surface, color, and pygame Rect object as an input parameter and draws a rectangle on the surface. Example 1:   Drawing a rectangle and filled it with blue color. from pygame.locals import * def main (): pygame.init() DISPLAY=pygame.display.set_mode(( 500 , 400 ) , 0 , 32 ) BLUE=( 0 , 0 , 255 ) pygame.draw.rect(DISPLAY , BLUE , ( 200 , 150 , 100 , 50 )) while True : for event

The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package from 2 cm to 400 cm or 1” to 13 feet. The operation is not affected by sunlight or black material, although acoustically, soft materials like cloth can be difficult to detect. It comes complete with ultrasonic transmitter and receiver module. Components required Breadboard x 1 (optional) Arduino Uno R3 x 1 Ultrasonic Sensor (HC-SR04) x 1 Jumper x 4 (Female-Male) Procedure Follow the circuit diagram and hook up the components on the breadboard as shown in the image given below.
