Milling: milling the board was pretty tricky, because the 328P-AU have a very tiny footprint, the pads are very close each oder (only 0,25mm). To mill the board I have used the same process described in the electronics production module.

Arduino Output code

					//define all the output pins
					#define R1 10
					#define R2 9
					#define R3 6
					#define MOT 11
					#define COMP 5
					
					void setup() {
					  //initialize the serial port
					  Serial.begin(9600);
					  //set the pins as an output
					  pinMode(R1, OUTPUT);
					  pinMode(R2, OUTPUT);
					  pinMode(R3, OUTPUT);
					  pinMode(MOT, OUTPUT);
					  pinMode(COMP, OUTPUT);
					}
					
					void loop() {
					  //turn on the output
					  //and set up the motor speed
					  analogWrite(MOT, 160);
					  digitalWrite(R1, HIGH);
					  digitalWrite(R2, HIGH);
					  digitalWrite(R3, HIGH);
					  digitalWrite(COMP, HIGH);
					  //wait 5 second
					  delay(5000);
					  //turn off the output
					  //and slowdown the motor speed
					  analogWrite(MOT, 40);
					  digitalWrite(R1, LOW);
					  digitalWrite(R2, LOW);
					  digitalWrite(R3, LOW);
					  digitalWrite(COMP, LOW);
					  delay(5000);
					}
