Description: In this routine, we will use all the above sensors with OLED to joint test. The OLED uses menu to manage, so you can easily see the sensor values you have selected by menu options. And rotary encoder comes in handy here. By rotating the handle of rotary encoder, you can choose the sensor you want. By pressing the switch, you can enter into the selected sensor interface.

Second, program (please go to our official website www.sunfounder.com to download the example code by clicking LEARN -> Get Tutorials)

Third, compile the program

Fourth, burn the program into SunFounder Uno R3 board

After you have finished all the above steps, rotate the rotary encoder to select the sensor you want to know and press the switch on the rotary encoder, then you can enter into the corresponding sensor interface to see related information. The physical diagram is as shown in figure 30:
