Elect 707 Micro-Computer Applications 2011
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 1 st car send her a go condition as shown in the chart shown.
Car Hardwa re H- Bridge/ Relays PIC Zigbee Limit Switche s
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.
