Cell phone – based controller for a toy car

Abstract

Different methods and techniques have been used for both remote controlling and remote monitoring. With the advent and popularity of cellular phones , these phones can provide cheap, dependable and feasible technology to control a remote object and to monitor far away environmental parameters. In this system, it is proposed to use cellular phones as a new technological controlling technique to remotely navigate a toy car, and to request the measurement of some parameters from the car. The system needs a regular cellular phone to be attached to an internal microcontroller board of the toy car to accept commands, execute commands, and send measured parameters to the other phone. In order to achieve all these activities and services, a set of pre-programmed commands and data are stored in the microcontroller memory and considered the interface method between the cellular phone of the toy car and the users cellular phone. After the toys car control circuit accepts the commands, process execution will begin. The user should use only the pre-programmed commands, and follow the correct procedures to achieve both navigation and monitoring operations.
