According to the temperature sensed by temperature and humidity sensor the resistance of the fan will be adjusted to change the fan speed. It's fairly straightforward to use, however needs careful arrangement to grab information. DHT22, Arduino and LCD will get power from the same fan ...
In conclusion, this article discussed the ADXL320 acceleration measurement sensor and its application with the Arduino. We explored the functionality of the ADXL320 sensor, learned about its connection to the Arduino Uno R3, and provided guidance on writing code to measure acceleration in two directi...

The push button, wired in series with the 10 KΩ resistor, will provide a control signal to the Arduino, simulating a digital temperature sensor (like a thermostat). The 1N4001 silicon diode is used to suppress any back EMF produced by the DC motor being de-energized by the SSR...
Once the JSON string is deserialized, we have declared three variables to hold three parameters that are sent by the server, which is theLED_STATUSthe Temperature and Humidity data from the DHT22 sensor. Once we do that, we set up the display and print all the information to the OLE...
Next, declare the Arduino digital pin connected with the LED’s anode pin. It is pin 3 in our case. int ledPin = 3; Moreover, create an int variable called ‘sensorValue’ to hold the sensor value. int sensorValue = 0; Inside the setup() function, configure the ledPin as an outpu...
