Concept
A sealed DC motor spinning an impeller.
A little theory
Must be wet/primed; dry run overheats. Current ~100–200 mA. In the classroom, treat Mini Submersible Pump 3–6 V as a beginner part using DC 2-wire via MOSFET/relay. Typical India street price is about ₹40–₹120. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
