
Building a Zigbee controlled car that can
communicate with 2 other cars by sending
them its order.
◦ The car contains a Zigbee 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 1st car
send her a go condition as shown in the chart
shown.

Learn how to Program the PIC
Learn how to use Eagle.
Breif Zigbee introduction (Sunday, 18)
Design your Pcb board using Eagle (Phase 1)
Build your Pcb in the lab (Phase 2)
Install and wield your components.
Program the PIC
Test and deliver
(Phase 3)

Convert your car to be controlled via a remote
control zigbee board.
◦ Build a Pcb for a Remote control that can control
the car using Zigbee.
◦ Program the PIC in the remote to control the car.
◦ Test your program.
