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.

It works by controlling the motor speed through pulse-width modulation, regulating a series of pulses from the battery to the pump.

Below is the circuit's front and back which we completed and successfully tested last class
