Scratch and Mblock With Arduino Examples

 DHT-11 is a digital temperature and humidity sensor. It uses the capacitive humidity sensor and thermistor inside to measure the air around it. It transfers the data of these sensors to the digital output pin. In this application, we will measure the temperature and humidity in the environment with the DHT-11 Sensor.    A list of materials:   1-Arduino Uno 2-BreadBoard 3-1 x DHT-11 Sensor 4-Jumper Cables 5- LCD ı2c Modul We need your supplies. We connect the leg that writes the data of the DHT-11 Sensor we added to our breadboard, with a jumper cable, to the digital pin 8 of our arduino uno material, the leg that writes GND, with a jumper cable, and the leg that writes VCC to the GND (negative) terminal of the Ardunio Uno. The connection of the lcd i2c module is as follows; vcc is connected to vcc terminal, gnd-gnd terminal on arduino uno, sda and scl are connected to sda and scl terminals on arduino uno. The circuit diagram is given below. Code Part: In the Mblock 5

 NTC is a temperature sensitive sensor. In this application, we will make a temperature measurement with the NTC Sensor and make a fire alarm application using the Buzzer.     A list of materials:   1-Arduino Uno 2-BreadBoard 3-1 Buzzers 4-1 NTC Sensor 5-Jumper Cables 6-1 LEDs   We need your supplies. We connect the long leg of the Buzzer, which we added to our breadboard, with the jumper cable to the digital pin 11 in our ardunio uno material. We connect the short leg of the buzzer to the GND (negative) terminal of the Ardunio Uno with a jumper cable. NTC Sensor has 2 legs. Their legs are of equal length. We connect a resistor to one of the legs. We connect the end of the resistor to 5 Volts. We connect it to one of the analog pins with a cable from the leg to which we connect the resistor. I connected it as A0. We connect the other leg of the NTC to the GND (negative) terminal. We connect a resistor to the long leg of the LED. From this end, I connected it to the di

 In this application, we will make a parking sensor application using HC-SR04 Ultrasonic Distance Sensor and Buzzer.    A list of materials: 1-Arduino Uno 2-BreadBoard 3-1 Buzzers 4-1 x HC-SR04 Ultrasonic Distance Sensor 5-Jumper Cables   We need your supplies. We connect the long leg of Buzzer, which we added to our breadboard, with the jumper cable to the digital pin 10 in our ardunio uno material. We connect the short leg of the buzzer to the GND (negative) terminal of the Ardunio Uno with a jumper cable. HC-SR04 Ultrasonic Distance Sensor has 4 legs. We connect the leg that says VCC to 5V with a cable. I connected the leg that says Trigger to digital pin 9, the leg that writes Echo to digital pin 8, and the leg that writes GND to the GND terminal. 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 forever code from the control menu, we create a variable called Distance

 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

 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 c

 In this application, we will do an activity to keep the number of vehicles passing the red light at the scratch. 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 and green light, and finally, by painting only the green light, the sprite has 5 costumes in total. After adding our traffic light, we add a road image to the backdrops 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. Below are the codes that we will write inside the car sprite. Clicking the Green Flag hides the car, and we create a variable from the Variables menu to keep cars running through the red light. Initially let this variable be zero. Because if the game has been played and closed before

  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. Below are the codes that we will write inside the car1 sprite. Clicking the G
