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
