Running Firmata parallel to other functions

[mrburnette]

@rayk05

However, I want to implement the functions (which are running servos) to be loaded onto the Arduino along with the Firmata sketch, so that the only thing NodeRed does is give signals to the designated pins, while the functions in the Arduino run the motors based on the input to said pins.

Just write serial code to implement a State Machine. Construct your own commands to handle all needed functions. As an example (crude) of how such a code may function, envision a serial calculator with verbs" Add, Sub, Div, Mul..."
