In this article we will use a pair of XBee modules to build a simple wireless interface which will be used to wirelessly control a servo based pan and tilt system which can move my camera 45 degrees in any direction, left-right-forward-backwards.
Purpose & Overview of this project
The purpose of this project is actually to answer a question from the forums about how to make a pan and tilt system using servos and xbee modules. We'll place a camera atop the pan/tilt system and using some additional circuitry we will add a trigger for transmitting button presses wirlessly as well.
To accomplish this large task, we will use standard 1mW XBee Modules on breadboards, one as the transmitter, one as the receiver. Two HS-485 servos will be used in the pan and tilt system. Two PIC 18LF4520's will be used to add intelligence to the transmitter and receiver circuits telling the servos what to do and when receiver buttons have been pressed.
