/* AnalogReadSerial Reads an analog input on pin 0, prints the result to the Serial Monitor. Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu). Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

Libraries

No libraries — read from pin names and pinMode alone.

Pin contract

An immutable contract owned by the project. It survives level changes; on a target board only the physical pins are remapped.

Logical name	Pin	Direction	Signal	Declared as
A0	A0	in	analog	literal

This page passes no verification gate. Logic (simulator), electrical (ERC · DRC) and physical (your confirmation) verification each run separately inside a project.

Next step

Same sketch, from simulation to PCB

The code stays as it is. Run it on avr8js in the Playground; import it into a project and the 8-pass electrical verification, KiCad board generation and Gerber export follow.
