Using DS18B20 with 1602 LCD on Arduino
In this tutorial we start with a short easy to follow sketch to print text on a 1602 LCD using either direct connection to Arduino, or through I2C with a GPIO expander.
Then we add the DS18B20 digital thermometer and display the temperature on an LCD with minimal complexity to get it up and running.
Finally everything is merged into one project, some more advanced commands are used, and both LCDs are used simultaneously to illustrate how to control multiple devices.
