Day and Night Application With Mblock and Arduino

 Together with the Mblock program, we will make Night and Day Applications. When we run the Night and Day Application, which we made together with the Mblock program, when we press the letter "A" on the keyboard, a brighter scene decor will appear on the screen and the word "Gündüz" will appear and our LED will not light. When we press the letter "S", a darker stage decoration will appear next night and our LED will light up in the circuit we have created. We will make this application in the Mblock program. Before moving on to the codes, the list of materials to be stretched in our led circuit:

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.

Day and Night Application With Mblock and Arduino

Now let's come to our codes in mBlock; City with water (the dark one) city with water 2 (the bright one) in the Mblock backdrop library as a scene decor.

Mblock and Arduino examples


I added a sprites to the scene.

Mblock and Arduino codes


The code part is as follows:



When the "a" key is pressed on the keyboard, switch to the bright decor (we add it from the Looks menu) and we do not turn on our led with the code to set the digital pin 8 low (we add it from the Robots menu) and the speech bubble called dummy Day appears (we add it from the Looks menu). When the "S" key is pressed, it will switch to the dark decor, and by making the digital pin 8 high, we make it light up. We make the sprites think it's night. 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 upload the codes we wrote with the firmware update from the connect menu again to our arduino board. Thus, our program becomes ready to run.


 To download the source code of the program CLICK HERE

To download the source code of the program CLICK HERE  (This program ise done with mblock 5 version)

Note: You can upload the codes to the arduino uno board by pressing the connect and upload buttons at the bottom of the screen respectively.





First of all, we add the upload mode broadcast extension from the extensions section to be able to use the sprite. So we can send any message to the sprite we will use. we add the same plugin with sprite selected



After adding the arduino uno from the devices section, we write the following codes in it. We turn on or off the led according to the message from the sprite.



When the "a" key is pressed on the keyboard, switch to the bright decor  and we do not turn on our led with the code to set the digital pin 8 low  and the speech bubble called daytime and sending a message to the arduino uno. If the value of the message is A. Day appears (we add it from the Looks menu). When the "s" key is pressed, it will switch to the dark decor and sending a message to the arduino uno. If the value of the message is S,

Pacman Game on Scratch Program

 We will make an example of pacman game making with Scratch. Before starting the Pacman Game example that we will do with Scratch, we download the background for the pacman game from the internet and add it to the backdrop part in Scratch. When the background I downloaded was dark, I painted the dark colors with white. I made the borders thicker. After adding our background to our work, it came to creating the pacman character. I drew a full circle in yellow for the Pacman character. After that, I drew two lines towards the center using the line tool. I erased the remaining part with an eraser. If you want, you can use the erase background tool to erase between two black lines. Thus, our pacman character took his place with his mouth open. I created a guide dot right in front of the pacman character. This will keep us moving. I created a red dot. It's a little obvious, you can make this red dot smaller if you want, you can give it another color and make it more invisible. After cre...

How To Make Bubble Shooter Game on Scratch Program

 We will make a bubble shooter game example with Scratch. I am adding 3 balloons and a target picture for the bubble shooter game we will make with Scratch. (You can increase the number of balloons). Now I come to the codes to be written inside balloon1. Let the number of balloons popped when the green flag is clicked is 0. Thus, the remaining numbers from the previous game are reset. Let the balloons be hidden at first. Then, it will appear in a random place between the coordinates we have determined at a random time between 1-5 seconds, wait for 2 seconds, then hide. X: The coordinates between -218/144 are the coordinates of the far left and the right of the screen, Y:134/-235 are the coordinates of the top and bottom of the screen. It will appear randomly in these ranges If our balloon is aimed and hit by the target; Balloon shot news is released. When this news reaches our balloon, the balloon will be hidden. Copy and paste the same code above.   Then we say duplicate...

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...
