hardware : arduino micro

hardware circuit:


code:

#include<softwareserial.h>
softwareserial myserial(11,12);  //rx .tx
byte transitvalue = 0x00;

void setup() {
serial.begin(9600);
myserial.begin(9600);

}

void loop() {
 if(myserial.available())
 {
   transitvalue =myserial.read();
 }
serial.println((byte)transitvalue,hex);
serial.println((byte)transitvalue,bin);
delay(1000);

}
