Arduino Code - LM35 Temperature Sensor - OLED
- Open Arduino IDE, Go to Tools Manage Libraries
- Search “SSD1306”, then find the SSD1306 library by Adafruit
- Click Install button to install the library.
- You will be asked for intalling some other library dependencies
- Click Install All button to install all library dependencies.
- Copy the above code and open with Arduino IDE
- Click Upload button on Arduino IDE to upload code to Arduino
- Put the sensor on hot and cold water, or grasp the sensor by your hand
- See the result on OLED and Serial Monitor
※ NOTE THAT:
The about code automatically horizontal and vertical center aligns the text on OLED display
