 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 our previous application, I explained how to make a Traffic Light Application inArduino with Mblock . In this application, we will find the number of vehicles passing the red light by making additions to the mblock with the traffic light application First of all, we find a traffic light on the internet. At first, all the lamps are dark, by painting the red light, by painting the red and yellow light, by painting the yellow light, and finally, by painting the green  and green light, the sprite has 5 disguises in total. When each LED is on, which LED will light up, it will be disguised. After adding our traffic light, we add a road image to the background decor. In addition, we find a car picture on the Internet for the car that will pass on the road and add it. I drew a line on the road and painted it red in order to detect the people passing through the red light.   Now it's time to move the car.
