    <p>Digital mode - expects a <code>msg.payload</code> with either a 0 or 1 (or true or false),
    and will set the selected physical pin high or low depending on the value passed in.</p>
    <p>The initial value of the pin at deploy time can also be set to 0 or 1.</p>
    <h3>Settings</h3>
    <ul>
        <li>PIN: Choose a specific pin through simulated 40-pins component.</li>
        <li>BCM GPIO: Matched with chosen pin</li>
        <li>Initialize State: The initial value of the pin at deploy time can also be set to 0 or 1.</li>
