Configuring Your Raspberry Pi

I2C Configuration

To enable the I2C port on your Raspberry Pi, follow these steps (skip if already enabled; if unsure, proceed with the instructions).

  1. Log into your Raspberry Pi, open the Terminal, and enter the command below to access the Raspberry Pi Software Configuration Tool. (You can also access the terminal using SSH.)

    sudo raspi-config

  2. Go to Interfacing options.

    Note

    Use the up and down arrow keys to move the highlighted selection between the options available. Pressing the right arrow key will jump out of the Options menu and take you to the <Select> and <Finish> buttons. Pressing left will take you back to the options. Alternatively, you can use the Tab key to switch between these.
