Dr. Arduino

Harley Arduino, most commonly known as Dr. Arduino or just Arduino, is a mechanic in Valleyville. She has a workshop located in The Robot Kingdom, and for sake of convenience, lives there as well. His living space is connected to the workshop itself, though he rarely uses it, falling asleep at his work desk most of the time.

Appearance
Dr. Arduino is a 7ft-even Hispanic human with brown hair and medium brown skin. He appears entirely human apart from the fact she has 2 sets of arm, the lower set of which are robotic. As far as gender expression, Dr. Arduino tries his best to be perceived as androgynous as physically possible. His assigned gender at birth is completely unknown, and when asked she will not provide any comprehensible straight answer. Arduino only uses the masculine and feminine binary pronouns, honorifics, and terms, and does not use gender neutral ones.

Season 1
Originally, she used to wear a white unbuttoned lab coat with dark green gloves over it, and under the lab coat was a turquoise sweater. He had dark grey pants and black shoes, and on her face, he wore green safety goggles which obscure his eyes. Her official eye color was unknown, as he'd never been seen without these goggles on. Upon asking her about his true eye appearance, she would give out some outlandish and obvious lie, and this answer would change every time you ask him. In the season 1 finale, he briefly changes to a black eyepatch, green sweater, black cargo pants and a belt with a gun holster, and black boots.

Season 2
In season 2, his clothing reference was changed, and he now wears a green long sleeve, black pants, a toolbelt, grey shoes and grey gloves on her lower set of arms. After gaining more confidence around people by being partners with Sadie, Arduino was comfortable enough to drop the goggles outside of work and instead wears a black eyepatch (which is sometimes switched out for eyepatches with different designs for special occasions).

Role in Valleyville
Arduino is a mechanic which specializes in creating and repairing sentient robots in Valleyville. His occupation would be most accurately compared to a doctor in human society. Most of her job consists of robot families commissioning him to build a toddler or child robot for them, though Arduino accepts commissions from anyone for any reason. He also does physical repairs, debugs, and check-ups for any robot that asks.

Backstory
Arduino was born and raised somewhere outside of The Valley. The exact place he came from is unknown, though she grew up with her father, sister, and brother. He lived outside of Valleyville until he graduated high school, moving to Valleyville alone after graduating. She attended college in Valleyville.

It was revealed that Dr. Arduino had originally lived a very nice life outside of the valley, being very popular in his high school and very skilled with robotics even as a teenager, as well as working on cars alongside his dad. She had only moved to Valleyville after a project exploded in his face, resulting in scarring of the left of her face and the loss of his left eye. Because of this, his popularity dropped immensely and the humiliation and bullying had become so bad her parents opted to send him to Valleyville instead.
