Apple Picking Game with Potentiometer- Mblock with Arduino

 Before moving on to this application, we had done the LEDLighting with the Potentiometer. You can learn the installation of the potentiometer and the necessary materials here.

 Let's write our codes in the Mblock program. First of all, find a background from the internet, we change the background from the scene section.


I add 3 apples (you can increase the number of apples) and 1 basket from the new puppet part.

 

Here are the codes in Apples:


Since the green flag is clicked, we add the code to get our variable number of apples 0, which we created from the data section. If we do not add this, the number of apples collected will continue from where it left off if the game was played before. We take the code that generates random numbers from the operations menu and add the code that generates random numbers into the code to go to the x and y point that we added from the movement menu so that the apples come out randomly in a horizontal place. Here, we write the starting points in the range in which we want the apple to come out. and we make the apple appear. Apple, we're adding the repeat code from the control menu to make it move from top to bottom. Our apple will move down, that is, on the y-axis, for this we add the code to increase y from the movement menu. However, we say increase y by -2 since our direction of movement will move in the downward direction, that is, in the negative direction. Here we have two possibilities. 1. The apple can touch the bottom edge of the screen by constantly moving down. In this case, we want our apple to be hidden. We are using hide from view code. Since we add 3 apples, we wait for 2 seconds and then make them appear randomly in the coordinates we will determine. Our second possibility is that if the apples touch the basket, when the apple touches the basket, the apple will be hidden and the news of the touch to the basket will be released. Because when this news is released, the number of apples collected will increase by one. The hidden apple will appear to spawn from a random location after 2 seconds. Thus, with 3 apples, we will ensure the emergence and movement of the apple continuously.

 

Codes in Basket:

When the green flag is clicked, I set the remaining time to 10 for testing purposes. You can extend this period. If it is seconds, we first check the remaining time in the repeat code. If the remaining time is 0 we add the stop all code which will stop all the puppets. If the remaining time is not 0, wait 1 second and add the code increment -1, which will decrease the remaining time by 1. When the apples touched the basket, the news was spread that the apples touched the basket. When this news comes, we increase the number of apples collected by 1. The movement of the basket will move according to the value of the potentiometer. The potentiometer is connected to our A(0) pin on our Arduino board, and if this value is between 0 and 512, it will move to the right. If it is between 512 and 1024, it will move to the left. For this, it is sufficient to turn the potentiometer to the right and left.

Note: In order to run these codes, after connecting our arduino board and circuit to the computer with a usb cable, we first select the Serial port from the Connect menu, then select the port to which our arduino board is connected. After selecting it, we will have uploaded the codes we wrote with the firmware update from the connect menu again to our arduino board. Thus, our program becomes ready to run.

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...
