I took out my arduino chip from my board and followed the instructions to put it on a breadboard here: http://itp.nyu.edu/physcomp/uploads/arduinobb_09.jpg Everything works fine but when I plug in an XBee, the code doesnt work the way it should.
The code I was using was two simple statements in the setup() function
Starting the Serial port:
Serial.begin(9600);
Printing a line:
Serial.println("Hello World");
The problem is that it repeatedly sends this message over the XBee and I can see from the receiver XBee that it rapidly sends "Hello World" over and over. Also, if I check the voltage supplied by the voltage regulator, it is only 3.7 volts rather than 5 volts.
Why is this happening?
The likely explanation as to why setup() is being executed continually is that the chip is being repeatedly reset. This is likely to be related to the low voltage you are seeing.
