I used the voltage divider method to get 3vdc to pin 3, but you can also use a 3vdc battery if you desire. You can also try to change the resistor values so they do not use 100mA as my solution does. I did not know how much current pin 3 required, so I chose low resistor values. I suspect you could use a much higher value and get the same result without using all that current. I left the values as I have used them, because I know it works, but feel free to experiment if you use this method which you would probably want to optimize if you plan on using a battery for your 5vdc source.</ins></div></td></tr>
