Uses Arduino UNO to talk to REV 2M Distance Sensor. Writes LED PIN (13) high if closer than fixed threshold. Intended to connect to roboRIO DIO pin to avoid roboRIO i2c known issue https://docs.wpilib.org/en/stable/docs/yearly-overview/known-issues.html#onboard-i2c-causing-system-lockups https://www.revrobotics.com/rev-31-1505/ https://github.com/pololu/vl53l0x-arduino
