Concept
Switching regulator stores energy in an inductor; much less heat than linear.
A little theory
PWM + LC filter. Efficiency often 75–90 %. In the classroom, treat LM2596 Buck Converter Module as a intermediate part using Screw terminals. Typical India street price is about ₹40–₹90. 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
Set output with the pot using a multimeter BEFORE connecting the MCU.
