Computer Input and Output Hardware Units Game Making with Scratch

 In this application, we will make a game of computer input and output hardware units with the scratch program. The game will be as follows; The user will be prompted to drag and drop pieces of hardware into the input and output device areas. If the user places the piece of equipment in the correct area, he will receive 5 points, if he places it in the wrong area, he will lose -5 points. Now it's time to code our game in the scratch program.



First of all, we draw the sprites on which we will place the input and output hardware units from the costumes menu. After that, we add the hardware units that we downloaded to our computer before and the emoji expressions and the sound of applause when it is right or wrong.


Let's come to the code part;

 If the person playing the application places the equipment in the correct area, he will gain 5 points, if he places it in the wrong place, he will lose -5 points. For this we need a variable to hold the score. We create a variable called score from the Variables menu.


When the green flag is clicked, when the application restarts, we set the score to 0 and fix the screen hardware piece somewhere on the screen. We do this with the command to go to x and y coordinates from the Motion menu. There are two possibilities for us to move this piece of hardware wherever we want, the first is pressing the mouse, the second is by choosing the colors of the place we want to move it. For this, we take the "If" code into the repeat code from the control menu, and we get the code and from the "Operators", which will meet our two conditions at the same time, into the space inside. Click the mouse in the "Sensing" menu? and we place the color codes. Since the display is the output unit of the hardware part, first of all, we choose the color of the area where the output devices are collected, that color is pink. If these two conditions are met, the correct news is released. For each piece of hardware, the right news is released with a different name. Then, after leaving the screen hardware piece in that area, we determine a certain coordinate from the motion menu to go to a certain place and make the piece go there. So we get 5 points. With the stop code that we added from the control menu, we stop all codes related to the screen or that hardware from working. You can also move it to the wrong place of the screen. Again, we control this with the And command. If the mouse is pressed and the yellow color is touched, the screen image goes to the coordinate we have determined, which is also in the pink area. We are warned that this hardware is an Output device and we lose -5 points.



If she put the hardware in the right area, when the correct news is released, we increase the score variable by 5 points and start the clap sound


If we've dragged the gear into the wrong area, we're reducing the score variable by -5 points when false news is released.


Clap icon pops code when we drag and drop the hardware to the right area


Code for the sad emoticon icon to pop up when we drag and drop hardware to the wrong area

Since the codes and logic in other hardware parts are the same, I did not include them one by one.

How to Make Countdown a Maze Game on Scratch

  We will make a countdown maze game example with Scratch. For the countdown maze game example we will make with Scratch, we upload the maze picture we downloaded to our computer from the scene section to the scratch program. Then we select the object that we will move in the maze section from the choose a sprite section and add it to our scene. We bring the object to be moved to the red point, which is the starting point. First of all, we create a variable named Duration to calculate the elapsed time in the maze from the "Variables" menu When you click the green flag, set the duration variable to 40. Our goal is to get the ball to the finish line in 40 seconds. If our ball object to move, we give the x and y coordinates to go to the red starting point. Our object will not move only once. First of all, we add the "Forever" code from the "Control" menu so that it moves every time we press the arrow key. Now it's time to check which direction key is pres...

Blinking LED with Mblock and Arduino

  We will blink the led with the mblock program. The list of materials that will be used in our led circuit before moving on to the codes of the application we will make with the Mblock program: 1-Arduino Uno 2-BreadBoard 3-LED 4-220Ω Resistor 5-Jumper Cables We need supplies. We add a 220 ohm resistor to the long leg of the Led that we added to our breadboard. We connect one leg of the resistor with a jumper cable to the digital pin 8 of our ardunio uno material (You can connect your jumper cable to any digital pin you want between 2-13). The circuit diagram is below. Now let's come to our codes in mBlock; In the Mblock program, we add the Arduino program starter code from the Robots menu. After adding the forever from the control menu, we add the code to whichever digital pin we connected our led to the inside of the "Robots menu ... we add the code to make the pin low. We write 8 because I connect it to digital pin 8. We do not light our led with the code of s...
