 *Sketch of the circuit. The labels D2, A2, etc. represent the digital and analog pins of the Arduino micro. Resistor and capacitor values can be seen in the figure. The water pump is controlled via the Arduino using the transistor. To prevent the inductive voltage pulse on turnoff of the water pump, a flyback diode was connected in parallel.*
