You can use the two general purpose I/O connectors GPIO0 and GPIO1 to connect te DE2 to your own circuits (including your resistors). The GPIO pins can be programmed as output by which you get either a 3.3 volt or 0 volt output. (By using the jumpers you can also choose an other high output voltage). You can also use the pins as input and then the result read will depend on the voltage at the input pin being higher or lower than the threshold voltage.
