Rangkaian percobaan 2
Rangkaian yang disusun terdiri dari 2 buah Arduino, lalu untuk outputan dari pin 2 dihubungkan ke button, kaki 7 dihubungkan ke kaki LED begitu pula pada bagian Arduino Slave. Untuk pin 13 12 11 sendiri saling dihubungkan karena pada pin tersebut kita gunakan sebagai data transfer antar mikroprosesor, dimana ada pin MOSI, pin MISO dan pin SCLK yang saling terhubung. untuk sinyal Clock sendiri digunakan untuk sinkronisasi antar arduino.
dan program yang ditulis sebagai berikut :
//GERINANDA
//2010953004
//KEL 11
// Percobaan 1 Kondisi 16
////Ubah button menjadi saklar SPST
//MASTER
#include<SPI.h> //Library for SPI
#define LED 7
#define ipbutton 2
int buttonvalue;
int x;
void setup (void)
{
Serial.begin(9600); //Starts Serial Communication at Baud Rate 9600
pinMode(ipbutton,INPUT); //Sets pin 2 as input
pinMode(LED,OUTPUT); //Sets pin 7 as Output
SPI.begin(); //Begins the SPI commnuication
SPI.setClockDivider(SPI_CLOCK_DIV8); //Sets clock for SPI communication at 8 (16/8=2Mhz)
digitalWrite(SS,HIGH); // Setting SlaveSelect as HIGH
}
void loop(void)
{
byte Mastersend,Mastereceive;
buttonvalue = digitalRead(ipbutton); //Reads the status of the pin 2
if(buttonvalue == HIGH) //Logic for Setting x value
{
x = 1;
}
else
{
x = 0;
}
digitalWrite(SS, LOW); //Starts communication with Slave
Mastersend = x;
Mastereceive=SPI.transfer(Mastersend); //Send the mastersend value to slave
if(Mastereceive == 1) //Logic for setting the LED output
{
digitalWrite(LED,HIGH); //Sets pin 7 HIGH
Serial.println("Master LED ON");
}
else
{
digitalWrite(LED,LOW); //Sets pin 7 LOW
Serial.println("Master LED OFF");
}
delay(1000);
}
