+// Wire Master Reader
+// by Nicholas Zambetti <http://www.zambetti.com>
+
+// Demonstrates use of the Wire library
+// Reads data from an I2C/TWI slave device
+// Refer to the "Wire Slave Sender" example for use with this
+
+// Created 29 March 2006
+
+// This example code is in the public domain.
+
+
+#include <Wire.h>
+
+void setup()
+{
+ Wire.begin(); // join i2c bus (address optional for master)
+ Serial.begin(9600); // start serial for output
+}
+
+void loop()
+{
+ Wire.requestFrom(2, 6); // request 6 bytes from slave device #2
+
+ while(Wire.available()) // slave may send less than requested
+ {
+ char c = Wire.read(); // receive a byte as character
+ Serial.print(c); // print the character
+ }
