Building a
Z
igbee

controlled car that can
communicate with
2
other cars by sending
them its order.


The car contains a
Z
igbee

module, as well as a PIC
programmed to order and take orders.


The car should got a limit switch that stop the car
when reach an obstacle


The next car should start as soon as the
1
st

car
send her a go condition as shown in the chart
shown.
