1. A method of regulating a motor, comprising:
map a voltage value input of a first value into a voltage value output of a second value across a triode via an analog switching circuit, the triode being configured to facilitate power to the motor;
compare the second value with a positive comparison voltage value;
provide an electrical signal to an inhibition switch in response to the second value being less than the positive comparison voltage value and greater than a predetermined threshold,
interrupt a trigger signal from a controller intended for a triac upon receipt of the electrical signal to inhibit the triac from initiating operation; and
compare the second value with a negative comparison voltage value, wherein the positive and negative comparisons include using values from a positive supply lead and negative supply lead; and
provide an electrical signal to the inhibition switch in response to the second value being greater than the negative comparison voltage value.
