Enable UART

If you burned the image successfully, you should see a folder named boot appear. If it doesn't magically appear once the burn is complete, try removing and reinserting the SD card into your computer.

Find the file named config.txt and open it in a text editor.

Scroll to the bottom of the file and add the following lines of text.

# Enable UART
enable_uart=1

Save the file. Safely remove the SD card from your computer. Put the SD card in to the Pi Zero.

We're so close!
