Traffic Light with Mblock

We will make a traffic light application with the Mblock program. Before moving on to the codes, the list of materials we will need in our traffic light circuit:

1-Arduino Uno

2-BreadBoard

3-3 LEDs

4-3 pieces of 220Ω Resistor

5-Jumper Cables

We need supplies.

Note: We need LEDs that give red, yellow, green light. If you are going to use white colored leds, you need to identify the leds that give the above 3 colors one by one before the application.

We add 220 ohm resistors to the long leg of the LEDs we add to our breadboard. We connect one leg of the resistors with a jumper cable to the digital pins 2,3,4 on our ardunio uno material (I connected the green led to the digital pin 2, the yellow led to the number 3, and the red led to the number 4). We connect it to the GND (negative) terminal. The circuit diagram is given 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 code of repeat continuously from the control menu, we add the code to whichever digital pin we connected our led to from the "Robots menu... Set pin high, set digital pin no. 3 low, set digital pin no. 4 low, we only light up our red led, our other 2 leds do not light. With the 10 second wait code we added in this event control menu, the red light will turn on for 10 seconds, the green and yellow leds will not light up. After 10 seconds, we make the digital pins 4 and 3 high so that the red and yellow leds light up together for 2 seconds. Then, by making the digital pin 2 high, we make the green led light up for 5 seconds. We make the other 2 leds go down by making them low. The last operation is The yellow and green leds are turned on together, after that, the operations return to the beginning with the repeat code and this event will be repeated continuously. In order for us 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, let's choose the port to which our arduino board is connected from there. By pressing the Upload to Arduino button, we send the codes we wrote to our Arduino board and upload them. Thus, our program becomes ready to run.

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...

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 start...
