WEEK ASSIGNMENT:

Networking and Communications

Design and build a wired &/or wireless network connecting at least two processors

 

 

 

 

 

Device connections

For this week activity we need to connect two processors, so we decide to use a Attiny44A micro-controller and a Arduino Mega2560 with a button and a  LED in each one, so the LED connected to a processor only turn on when the other processor button is activate

We use the attiny44A micro-controller Board made in activity six, based in Fab Academy Hello-World board:

 

 

 

 

 

 

 

DESIGN  FILES

For the Network we use an Attiny44A and a Arduino Mega 2560. The schematic diagram of the Serial Network connection:

 

 

 

 

 

 

 

Attiny44A Code:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(0, 1); // RX, TX

//Variables

  int LED=8;

  int BOTON=7;

  int DATO=HIGH;

 

void setup() {

  pinMode(LED, OUTPUT);

  pinMode(BOTON,INPUT);

  mySerial.begin(9600);

}

 

void loop() {

 mySerial.write(digitalRead(BOTON));

 delay(100);

 

 if(mySerial.available()){

 DATO=mySerial.read();

 }

      if(DATO==HIGH)

     digitalWrite(LED,HIGH);

     else

     digitalWrite(LED,LOW);

}

 

Arduino Mega2560 Code:

//Variables

  int LED=13;

  int BOTON=7;

  int DATO=HIGH;

 

void setup() {

  pinMode(LED, OUTPUT);

  pinMode(BOTON,INPUT);

  Serial3.begin(9600);

}

 

void loop() {

 Serial3.write(digitalRead(BOTON));

 delay(110);

 

 if(Serial3.available()){

 DATO=Serial3.read();

 }

      if(DATO==HIGH)

     digitalWrite(LED,HIGH);

     else

     digitalWrite(LED,LOW);

}
