Install the Slide Switches
==========================
*Cow Pi mk1f: Arduino Nano form factor,* |i2c-italics| *communication*

In this section, you will install the "slide" switches that toggle between their two positions, holding their position until toggled again.
We will wire them such that when a switch is toggled to the left, it will produce a 0, and when it is toggled to the right, it will produce a 1.
:numref:`mk1fSwitchDiagram` shows a diagram of the wiring for the slide switches.

When you have finished setting up the switches' wiring, there should be the electrical connections described in :numref:`mk1fTableSwitchSPDT`.
