The LM35 temperature sensor has 3 pins –VCC, GND and Analog Output Pin. Each of these pins has a separate function which is mentioned below. VCC Pin : This is the power pin of the sensor which can be ...

Setup Function: setup (): Initializes serial communication at 9600 baud rate. Sets the LED pin (led) as an output. Sets the LM35 pin (LM) as an input. Loop Function: loop (): Reads the analog value ...

Data Visualization: o Real-time temperature and humidity readings are sent to the serial monitor every second, providing a clear demonstration of sensor performance. Circuit Diagram The circuit ...

DS18b20 Temperature Sensor: In-Depth The DS18B20 is a digital thermometer that can provide 9-bit to 12-bit resolution and can measure temperatures from -55°C to +125°C. This is a unique chip designed ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

You also need to solder 5V and GND pins of Arduino for power supply to the Veroboard. If you are using the DHT22 sensor instead of the module, make sure you connect a 5-kilo-ohm pull-up resistor at ...

Pinout diagram Other changes include the replacement of the power supply chip (MPM3610 for MP2322), the addition of a VUSB soldering jumper on the top side of the board, and new test points for USB, ...
