Embodiments described herein relate to a light sensing system. In one embodiment, the light sensing system may include a microprocessor including an input pin configured to receive a first voltage from a light sensor. The light sensing system may also include a pull-up resistor coupled to the input pin. The pull-up resistor may include a first gate. The light sensing system may further include a pull-down resistor coupled to the input pin. The pull-down resistor may include a second gate. The first and second gates may allow for connecting or disconnecting the pull-up and pull-down resistors based on the amount or intensity of light detected by the light sensor.
