Adjustable Mist

Thinking how to make our misting system better developed for the consumer, we decided to implement a circuit which adjusts the amount of mist that the pump outputs. The circuit was small and fairly inexpensive as it had to be soldered together, however should easily fit in our housing unit. It works by controlling the motor speed through pulse-width modulation, regulating a series of pulses from the battery to the pump.
