Enable I2C Interface(Important)

Here we are using the Raspberry Pi’s I2C interfaces, but by default they are disabled, so we need to enable them first.

  1. Input the following command:

    sudo raspi-config

  2. Choose Interfacing Options by press the down arrow key on your keyboard, then press the Enter key.

  5. After you select <Finish>, a pop-up will remind you that you need to reboot for the settings to take effect, select <Yes>.
