     "Next, inspect the data sheet for the Pico ([pico_datasheet.pdf](https://datasheets.raspberrypi.com/pico/pico-datasheet.pdf) - also save this PDF in the main folder you're using since it'll continue to be handy throughout this course). Specifically, look for figure 2 on page 4. Then use the following table to make all the correct connections. \n",
