How to use DS18B20 sensor with Arduino Uno and LCD display
Download the code here link;https://github.com/passion-tech/Hello...
In this code, we use the OneWire and DallasTemperature libraries to interface with the DS18B20 temperature sensor. The LiquidCrystal library is used to display the temperature on the 2x16 LCD display.
We begin by initializing the serial communication and LCD display in the setup() function. We then call sensors.begin() to start up the temperature sensor library.
In the loop() function, we call sensors.requestTemperatures() to issue a temperature reading to the sensor, and then use sensors.getTempCByIndex(0) to retrieve the temperature in Celsius. We then use the lcd.setCursor() and lcd.print() functions to display the temperature on the LCD display.
Finally, we use the Serial.print() function to print the temperature to the serial monitor for debugging purposes, and then wait for 1 second using the delay() function before taking another reading.
