Xbee doorbell project

Posted on Feb 6, 2014

When you press a start button, the arduino picks a random 4 diget code and flashes lights to show the code. When you repeat the code in the other buttons, the XBee will send a message to the other XBee, which will ring the bell. int bell=5; void setup(){ pinMode(bell, OUTPUT); Serial. begin(9600); } void loop(){ if(Serial. available()>0){ if(Serial. read()=`D`)
