Adafruit writes of MHO the Resistor, "MHO has a laid-back, passive personality. He likes to do as little work as possible, and prefers to simply let the world happen around him. MHO is kind of a hippy, and is very quiet and gentle. He is best friends with Ruby, the red LED, who shares his idealism, though he's often reluctant to go off with her on her adventures because he thinks they will probably end up in trouble. MHO has sort of a nasally, hippie voice (California accent, but not a surfer). His catch phrase is 'no worries, man. it's all easy.'"
