Since the Trinket would not accept programming an Arduino Mini Pro replaced it because it was in stock. This unit is unfortunately 3.3V which may cause issues with the 5V relay. Arduino Mini Pros have an onboard voltage regulator so no different wiring was necessary. Pin programming was disregarded in order to line up the GND, pin2, and pin3 from the Arduino to the ultrasonic distance sensor. The three pins happen to be in the desired order. Long wires were run through the holes of each and soldered in place before trimming them.This lead to a very small clearance. The pin assignment in the program may have to be updated.
