LED Lighting with Potentiometer

We will make this application in the Mblock program. Before moving on to the codes, the list of materials to be needed in our potentiometer and led burning circuit:

1-Arduino Uno

2-BreadBoard

3-1 pcs LED

4-1 pcs 220Ω Resistor

5-Jumper Cables

6-Potentiometer

We need these supplies.

We add 220 ohm resistors to the long leg of the Led, which we added to our breadboard. We connect one leg of the resistor with a jumper cable to digital pin 8 in our ardunio uno material. We connect the short leg of the LED to the GND (negative) terminal of the Ardunio Uno with a jumper cable. The potentiometer has 3 legs. We connect the middle leg to the Analog pins with a cable. I connected it to analog pin A0. We connect the leg on the protruding part of the potentiometer with a 5V cable. We connect it to GND with the other leg. The circuit diagram is given below.

Code part;

In the Mblock program, we add the Arduino program starter code from the Robots menu. After adding the repeat code continuously from the control menu, we add the code to whichever digital pin we connected our led to from the "Robots menu ... If it is not, we check it with the command.If the value of the potentiometer on the A0 pin is less than 512, set pin 8 high and turn on our led (if it is, we add the green code in the operations menu and the other code in the robots menu) If the value is greater than 512, our led will turn on. In order for us to run these codes, we connect our arduino board and circuit to the computer with a usb cable, first we select the Serial port from the Connect menu, let's choose the port to which our arduino board is connected from there. Arduino Uno from the cards menu (or choose which board you are using) After selecting, Edit Select the Arduino mode from the menu and press the Upload to Arduino button, we will send the codes we have written to our Arduino board. 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 Balloon1 and

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
