Thanks for the advice! Firstly, I certainly didn't intend each function to run in sequence as you describe. Rather, each should occur simultaneously. The servos, motors, and steppers all should fire at the same time while the sensor value is less than 70. Does this mean that calling the functions within the loop is an altogether wrong method?As for power, I have an 8 amp, 12v supply. I'll disable the functions, one by one as you suggest.
To get everything to run concurrently, you will need to implement one or more Finite State Machines. Personally, because all the motors and things are doing such radically different actions, I'd probably create one separate FSM for each device, with the sensor triggering the start / end of them all at once.
