Breadboard aufbau (made with fritzing)

The hall effect sensor + Preamp

There is a hall effect sensor placed right over the valve of the airassist.

This valve is opened to enable a static airflow as soon as a laserjob starts and is disabled when the job ends.

Software documentation

this is partially wrong and needs correction

Arduino SENDS:

Code	Parameter	Expected reply	What does it mean	Example
I	<iButton ID>	A, N	IButton scanned	I:33-000000000000
X	NONE	O	Lazzzor shutdown button hit (eXit)	X
P	NONE	P	Ping! /Heartbeat	P

Raspberry sends:

Code	Parameter	Expected reply	What does it mean	Example
A	<username>	NONE	Authenticated	A:OVERFLO
N	NONE	NONE	Not authenticated (invalid Button)	N
O	NONE	NONE	Off (in response to X)	O
P	NONE	NONE	Heartbeat / PING	P
E	<Error>	NONE	Some Error occured	E:Network down!
