Concept
MOSFET: voltage on the gate lets current flow drain-to-source. Logic-level means 5 V gate is enough.
A little theory
N-channel low-side switch. PWM the gate for brightness/speed. Flyback diode across inductive loads. In the classroom, treat IRLZ44N Logic-Level N-MOSFET Module as a intermediate part using PWM gate. 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
Load from +V to drain, source to GND, gate from MCU via 100–220 Ω.
